Hint: Prefix bug IDs with https://bugs.openjdk.java.net/browse/ to reach the relevant JIRA entry. JAVA ENHANCEMENT PROPOSALS (JEP): JEP 338: Vector API (Incubator) Provide an initial iteration of an [incubator module](https://openjdk.java.net/jeps/11), `jdk.incubator.vector`, to express vector computations that reliably compile at runtime to optimal vector hardware instructions on supported CPU architectures and thus achieve superior performance to equivalent scalar computations. JEP 347: Enable C++14 Language Features Allow the use of C++14 language features in JDK C++ source code, and give specific guidance about which of those features may be used in HotSpot code. JEP 357: Migrate from Mercurial to Git Migrate the OpenJDK Community's source code repositories from Mercurial (hg) to Git. JEP 369: Migrate to GitHub Host the OpenJDK Community's Git repositories on [GitHub](https://www.github.com/). In concert with [JEP 357 (Migrate from Mercurial to Git)](https://openjdk.java.net/jeps/357), this would migrate all single-repository OpenJDK Projects to GitHub, including both [JDK feature releases](https://openjdk.java.net/projects/jdk/) and [JDK update releases](https://openjdk.java.net/projects/jdk-updates/) for versions 11 and later. JEP 376: ZGC: Concurrent Thread-Stack Processing Move ZGC thread-stack processing from safepoints to a concurrent phase. JEP 386: Alpine Linux Port Port the JDK to Alpine Linux, and to other Linux distributions that use musl as their primary C library, on both the x64 and AArch64 architectures, JEP 387: Elastic Metaspace Return unused HotSpot class-metadata (i.e., _metaspace_) memory to the operating system more promptly, reduce metaspace footprint, and simplify the metaspace code in order to reduce maintenance costs. JEP 388: Windows/AArch64 Port Port the JDK to Windows/AArch64. RELEASE NOTES, BY COMPONENT: core-libs/java.lang: JDK-8249160: Support supplementary characters in String case insensitive operations Case insensitive operations in `java.lang.String` class now correctly do case insensitive comparisons for supplementary characters (characters which have code point values over `U+FFFF`). For details, see the updates to the methods: ``` - compareToIgnoreCase(String other) - equalsIgnoreCase(String other) - regionMatches(boolean ignoreCase, ...) ``` For example, ``` "\ud801\udc00".equalsIgnoreCase("\ud801\udc28") ``` returns `true`, because '𐐀' ("\ud801\udc00") and '𐐨' ("\ud801\udc28") are equal to each other character in case insensitive comparison. core-libs/java.net: JDK-8252515: The default HttpClient implementation returns cancelable futures In this release, the default `HttpClient` returns *cancelable* futures. The default `HttpClient` is created by a call to `HttpClient.newHttpClient()`, or by invoking the `build` method on builders returned by `HttpClient.newBuilder()`. The implementation of the `sendAsync` methods in the default `HttpClient` now return `CompletableFuture` objects that are *cancelable*. Invoking `cancel(true)` on a *cancelable* future that is not completed, attempts to cancel the HTTP exchange in an effort to release underlying resources as soon as possible. More information can be obtained by reading the API documentation of the `HttpClient::sendAsync` methods. JDK-8251253: HttpClient.newHttpClient and HttpClient.Builder.build might throw UncheckedIOException Creation of an instance of `java.net.http.HttpClient` may fail with `UncheckedIOException` if the underlying resources required by the implementation cannot be allocated. Typically, this may happen if the underlying resources required to opening a `java.nio.channels.Selector` are not available. In this case `Selector.open()` will throw an `IOException` which the default implementation of `java.net.http.HttpClient` will wrap in an `UncheckedIOException`. The API documentation of `HttpClient.newHttpClient()` and `HttpClient.newBuilder().build()` have been updated to specify that `UncheckedIOException` may be thrown if the underlying resources required by the implementation cannot be allocated. Prior to this change, an undocumented `InternalError` would have been thrown. core-libs/java.util.logging: JDK-8247877: java.util.logging.LogRecord is updated to support long thread ids. In this release `java.util.logging.LogRecord` is updated to support long thread ids. `LogRecord::getThreadID` and `LogRecord::setThreadID` are deprecated: new accessors `LogRecord::getLongThreadID` and `LogRecord::setLongThreadID` are provided and should be used instead. The serial field `threadID` has been deprecated and a new serial field `longThreadID` that can support long values has been introduced. The deprecated `threadID` field is kept in the serial form for backward compatibility. Long thread ids that are less than `Integer.MAX_VALUE` are directly mapped to `threadID` (and `longThreadID` has the same value). For `longThreadID` greater than Integer.MAX_VALUE, a new negative value for the `int` `threadID` is synthesized, using a deterministic algorithm based on the `longThreadID` hash, and such that the resulting value is guaranteed to be a negative value. hotspot/runtime: JDK-8253225: Object monitors no longer keep strong references to their associated object When synchronization is performed on an object, an association is established between the object and the object monitor that implements the synchronization. In the past, the reference from a monitor to its associated object was a strong reference. These strong references would be observable through JVM TI functions that walk the heap (reported as `JVMTI_HEAP_ROOT_MONITOR` or `JVMTI_HEAP_REFERENCE_MONITOR`) and in heap dumps (reported as `HPROF_GC_ROOT_MONITOR_USED`). As of this release, a weak reference is used and these are not observable to JVM TI or heap dumps, and consequently `JVMTI_HEAP_ROOT_MONITOR`, `JVMTI_HEAP_REFERENCE_MONITOR` and `HPROF_GC_ROOT_MONITOR_USED` will no longer be reported. security-libs/java.security: JDK-8250756: Added Entrust Root Certification Authority - G4 certificate The following root certificate has been added to the cacerts truststore: ``` + Entrust + entrustrootcag4 DN: CN=Entrust Root Certification Authority - G4, OU="(c) 2015 Entrust, Inc. - for authorized use only", OU=See www.entrust.net/legal-terms, O="Entrust, Inc.", C=US ``` JDK-8250860: Added 3 SSL Corporation Root CA Certificates The following root certificates have been added to the cacerts truststore: ``` + SSL Corporation + sslrootrsaca DN: CN=SSL.com Root Certification Authority RSA, O=SSL Corporation, L=Houston, ST=Texas, C=US + sslrootevrsaca DN: CN=SSL.com EV Root Certification Authority RSA R2, O=SSL Corporation, L=Houston, ST=Texas, C=US + sslrooteccca DN: CN=SSL.com Root Certification Authority ECC, O=SSL Corporation, L=Houston, ST=Texas, C=US ``` JDK-8252392: Deprecate java.security.cert APIs that represent DNs as Principal or String objects The following APIs have been deprecated: ``` java.security.cert.X509Certificate.getIssuerDN() java.security.cert.X509Certificate.getSubjectDN() java.security.cert.X509CRL.getIssuerDN() java.security.cert.X509CertSelector.setIssuer(String) java.security.cert.X509CertSelector.setSubject(String) java.security.cert.X509CertSelector.getIssuerAsString() java.security.cert.X509CertSelector.getSubjectAsString() java.security.cert.X509CRLSelector.addIssuerName(String) ``` These APIs either take or return Distinguished Names as `Principal` or `String` objects which can cause issues due to loss of encoding information or differences when comparing names across different Principal implementations. All of them have alternative APIs which use `X500Principal` objects instead. JDK-8248263: jarsigner now preserves POSIX file permission attributes When signing a file that contains POSIX file permission attributes, `jarsigner` will now preserve these attributes in the newly signed file but will warn that these attributes are unsigned and not protected by the signature. The same warning will be printed during the `jarsigner -verify` operation for such files. Note that the `jar` tool does not read/write these attributes. This change would be more visible to tools like `unzip` where these attributes are preserved.
