files We have seen bugs related to the new locking which is used by default since JDK-8315880. It would be helpful to see the LockStack of a crashing JavaThread in hs_err files. JDK-8322345: Hotspot `hs_err` Files Now Print the Lock Stack A section containing the thread local lock stack has been added to `hs_err` report files. It only gets printed when the new lightweight locking mode is enabled (`-XX:LockingMode=2`). An example is given here with details about the locked objects omitted: ``` Lock stack of current Java thread (top to bottom): LockStack[1]: nsk.share.jdi.EventHandler ... LockStack[0]: java.util.Collections$SynchronizedRandomAccessList ... ``` It lists objects which are lightweight locked, through `synchronized` methods or statements, by the Java thread which is being analyzed. The object which has been locked most recently is printed first. Objects which are not lightweight locked are not displayed in this section.

https://git.openjdk.org/jdk/commit/336bbbe3895214a772e0f3aafb36277c46645ded, 57 day(s) ago Backports and Forwardports: 21: MISSING 17: Not affected 11: Not affected 8: Not affected Release Notes: JDK-8325944: Relax alignment of array elements Array element bases are no longer unconditionally aligned to 8 bytes. Instead, they are now aligned to their element type size. This improves footprint in some JVM modes. As Java array element alignment is not exposed to users, there is no impact on regular Java code that accesses individual elements. There are implications for bulk access methods. Unsafe accesses to arrays could now be unaligned. For example, `Unsafe.getLong(byteArray, BYTE_ARRAY_BASE_OFFSET + 0)` is not guaranteed to work on platforms that do not allow unaligned accesses, the workaround is `Unsafe.{get, put}Unaligned*` family of methods. The `ByteBuffer` and `VarHandle` APIs that allow views of `byte[]` are updated to reflect this change (JDK-8318966). Arrays that are acquired via `GetPrimitiveArrayCritical` should not be operated upon under the assumption of particular array base alignment as well. ---------------------------------------------------------------------------------------------------- JDK-8277417: C1 LIR instruction for load-klass Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8277417 Reporter: Roman Kennke Assignee: Roman Kennke Priority: P3 Components: hotspot/compiler Original Fix: 18: 18, JDK-8277417, https://git.openjdk.java.net/jdk/commit/99e4bda303f2c71972a125d0ecaf4cf986c8614a, 876 day(s) ago Backports and Forwardports: 21: Inherited 17: 17.0.9, JDK-8311637, https://git.openjdk.org/jdk17u-dev/commit/d7a59f37576afb1f0dbea5c2c804885b05cfb470, 288 day(s) ago 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8316659: assert(LockingMode != LM_LIGHTWEIGHT || flag == CCR0) failed: bad condition register Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8316659 Reporter: Martin Doerr Assignee: Martin Doerr Priority: P3 Components: hotspot/compiler Original Fix: 22: 22, JDK-8316659, https://git.openjdk.org/jdk/commit/6a4b6655507582ff685a999c21e7fd3992a39816, 212 day(s) ago Backports and Forwardports: 21: 21.0.2, JDK-8319384, https://git.openjdk.org/jdk21u/commit/3552d5a8989269eaa074da2b07a43a662adec54e, 168 day(s) ago 17: Not affected 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8329726: Use non-short forward jumps in lightweight locking Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8329726 Reporter: Y.
