Times A bug has been fixed that could cause long "Concurrent Process Non-Strong References" times with ZGC. The bug blocked the GC from making significant progress, and caused both latency and throughput issues for the Java application. The long times could be seen in the GC logs when running with `-Xlog:gc*`: ``` [17606.140s][info][gc,phases ] GC(719) Concurrent Process Non-Strong References 25781.928ms ```

Support for Solaris x86_64 Shenandoah is designed to be OS agnostic. However, minor differences in accepted language features in OS-specific tool chains can prevent it from being buildable on some operating systems. This release includes a change that enables Shenandoah builds with Solaris Studio, the default tool chain for the Solaris operating system. Testing shows that, after this change is applied, Shenandoah is fully operational on Solaris 11. ----------------------------------------------------------------------------------------------------

With the arrival of load reference barriers, it is possible to store the forwarding pointer in the then-unused memory of old copy of an object instead, for example use the old copy mark-word and encode the forwarding pointer there. This allows to eliminate the extra forwarding pointer word, and thus reduces memory footprint to that of regular GC. ---------------------------------------------------------------------------------------------------- JDK-8225014: Separate ShenandoahRootScanner method for object_iterate Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8225014 Reporter: Aleksey Shipilev Assignee: Zhengyu Gu Priority: P3 Components: hotspot/gc Original Fix: 13: 13, JDK-8225014, http://hg.openjdk.java.net/jdk/jdk/rev/f19a728d576d, 1645 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8225048: Shenandoah x86_32 support Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8225048 Reporter: Aleksey Shipilev Assignee: Aleksey Shipilev Priority: P3 Components: hotspot/gc Original Fix: 13: 13, JDK-8225048, http://hg.openjdk.java.net/jdk/jdk/rev/aa5eeb1a9871, 1643 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Not affected 8: Not affected Release Notes: JDK-8225531: Shenandoah x86_32 support Shenandoah now experimentally supports x86_32 in fully concurrent mode.

In many cases, this lead to taking a significant CPU toll when GC was running. In worst case, the system can be saturated with the GC work alone. In this release, the default number of concurrent and parallel Shenandoah GC threads is trimmed down to 1/4 and 1/2 of CPU threads, respectively. Users are advised to check if their installations benefit from these new defaults, or adjust `-XX:ConcGCThreads=#` or `-XX:ParallelGCThreads=#` if needed.

asynchronous object/region pinning When dealing with JNI Get*Critical methods, Shenandoah employs object/region pinning, instead of using the GCLocker. Until now, the inefficient pinning implementation have caused real-world scalability problems on workloads that use a lot of JNI, for example gzip and graphics. This was improved, and scalability bottleneck should be resolved. This fix was also backported to 8-shenandoah and 11-shenandoah. ---------------------------------------------------------------------------------------------------- JDK-8232730: Shenandoah: Traversal

barriers for Shenandoah Shenandoah used to employ the weak to-space invariant: allow reads to be done from the collection set while it is being evacuated, and evacuate objects on writes to them. This forced the implementation to have simple read barriers before every read accesses (including primitive ones), and complicated write barriers before every write access (including primitive ones), plus handling the cases where both copies of the objects are exposed (for example, in acmp). With this change, Shenandoah rewires the barriers to employ stronger to-space invariant: never expose objects in the collection set, evacuating them eagerly on reference load. Implementation rewires that used to be the write barrier handling code to every reference load, and removes other barriers (read, acmp, storeval barriers). The change makes simpler barrier interface, provides more opportunities for performance optimizations, reduces the maintenance burden. Even though Shenandoah makes more complicated read barriers with this change, the incidence of those barriers is lower, because there are no barriers on writes anymore, and only reference loads need to be handled. This makes the change performance neutral or performance-positive on many workloads, even with simpler optimization code. ---------------------------------------------------------------------------------------------------- JDK-8221848: Shenandoah: ArrayCopy post-barrier improvements Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8221848 Reporter: Roman Kennke Assignee: Roman Kennke Priority: P4 Components: hotspot/gc Original Fix: 13: 13, JDK-8221848, http://hg.openjdk.java.net/jdk/jdk/rev/13c02cc7a6e5, 1702 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8222129: Shenandoah: Missing CompareAndSwapP/N case in get_barrier_strength() Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8222129 Reporter: Roman Kennke Assignee: Roman Kennke Priority: P4 Components: hotspot/gc Original Fix: 13: 13, JDK-8222129, http://hg.openjdk.java.net/jdk/jdk/rev/0608ef3a7740, 1698 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8222130: Shenandoah should verify roots after pre-evacuation Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8222130 Reporter: Aleksey Shipilev Assignee: Aleksey Shipilev Priority: P4 Components: hotspot/gc Original Fix: 13: 13, JDK-8222130, http://hg.openjdk.java.net/jdk/jdk/rev/b9c461c02f7c, 1698 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8222185: Shenandoah should report "committed" as capacity Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8222185 Reporter: Aleksey Shipilev Assignee: Aleksey Shipilev Priority: P4 Components: hotspot/gc Original Fix: 13: 13, JDK-8222185, http://hg.openjdk.java.net/jdk/jdk/rev/511be32f3863, 1697 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Not affected 8: Not affected Release Notes: JDK-8226482: Shenandoah Logs Report Proper Committed Heap Size In previous releases, Shenandoah reported the max heap size as the current heap size.

The changes in this release also eliminate redundant logging lines that print reserved/committed/used memory sizes. This change makes Shenandoah GC logging more consistent with other GCs.

This requirement is relaxed now, and Shenandoah can run with the lowest `-Xms` that the shared JVM code can accept.

arraycopy improvements When handling Object[] arraycopy, Shenandoah used to evacuate array elements / fix references in the destination array after the copy. This is not efficient when multiple copies are done, as fixups would have to run on every copy. Plus, the fixups in the destination array do not improve the accesses to the source array. Unfortunately, this was the only way to deal with arraycopy until the GC API was extended. In JDK 14 with GC API improvements, Shenandoah is now able to fix up object arrays at source before the arraycopy, which improves performance and opens up other optimization opportunities. ---------------------------------------------------------------------------------------------------- JDK-8231087: Shenandoah: Self-fixing load reference barriers for C1/C2 Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8231087 Reporter: Roman Kennke Assignee: Roman Kennke Priority: P4 Components: hotspot/gc Original Fix: 14: 14, JDK-8231087, https://hg.openjdk.java.net/jdk/jdk/rev/bc0648405d67, 1535 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Not affected 8: Not affected Release Notes: JDK-8237013: Shenandoah self-fixing barriers Before this improvement, Shenandoah LRB barrier performance penalty for accessing forwarded objects involved resolving through the forwarding pointer, until the Update References phase fixed the affected references. A more efficient implementation ships now, where LRB self-fixes the forwarded reference on the same code path, eliminating continuous resolves for potentially hot accesses. Self-fixing is implemented for C1 and C2 (JDK-8231087), interpreter (JDK-8232992) and runtime (JDK-8232010) barriers.
