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, 320 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 eight bytes. Instead, they are now aligned to their element type size. This improves the 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. A workaround is the `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 a particular array base alignment. ---------------------------------------------------------------------------------------------------- JDK-8305895: Implement JEP 450: Compact Object Headers (Experimental) Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8305895 Reporter: Roman Kennke Assignee: Roman Kennke Priority: P4 Components: hotspot/runtime Original Fix: 24: 24, JDK-8305895, https://git.openjdk.org/jdk/commit/44ec501a41f4794259dd03cd168838e79334890e, 60 day(s) ago Backports and Forwardports: 21: MISSING 17: Not affected 11: Not affected 8: Not affected Release Notes: JDK-8307617: Compact Object Headers (Experimental) This release adds the experimental support for compact object headers.

This experimental feature can be enabled with -XX:+UnlockExperimentalVMOptions -XX:+UseCompactObjectHeaders.

Notes: JDK-8331076: The `LockingMode` Flag, Along With The `LM_LEGACY` And `LM_MONITOR` Modes Are Deprecated A new lightweight locking mechanism for object monitor locking was introduced in JDK 21 under JDK-8291555. The `LockingMode` flag was introduced to allow selection of this new mechanism (`LM_LIGHTWEIGHT`, value 2) in place of the default mechanism (`LM_LEGACY`, value 1). In JDK 23, the `LockingMode` default was changed to `LM_LIGHTWEIGHT`. In JDK 24, the `LockingMode` flag, along with the `LM_LEGACY` (1) and `LM_MONITOR` (0) modes are deprecated. The default locking mode `LM_LIGHTWEIGHT` will be the only internal implementation that is supported when these locking modes become obsolete in a future release. This is not expected to change any semantic behavior of Java monitor locking and it is expected to be performance neutral for almost all applications. ---------------------------------------------------------------------------------------------------- JDK-8315884: New Object to ObjectMonitor mapping Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8315884 Reporter: Coleen Phillimore Assignee: Axel Boldt-Christmas Priority: P4 Components: hotspot/runtime Original Fix: 24: 24, JDK-8315884, https://git.openjdk.org/jdk/commit/bd4160cea8b6b0fcf0507199ed76a12f5d0aaba9, 145 day(s) ago Backports and Forwardports: 21: Not affected 17: Not affected 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8344821: Test CheckDefaultArchiveFile.java fails if classes_coh.jsa is not present Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8344821 Reporter: David Holmes Assignee: Calvin Cheung Priority: P4 Components: hotspot/runtime Original Fix: 24: 24, JDK-8344821, https://git.openjdk.org/jdk/commit/246552674c5508ba350836389a0fa35716e776fb, 42 day(s) ago Backports and Forwardports: 21: Not affected 17: Not affected 11: Not affected 8: Not affected ---------------------------------------------------------------------------------------------------- JDK-8303823: [Lilliput] Inline initial LockStack stack Original Bug: URL: https://bugs.openjdk.org/browse/JDK-8303823 Reporter: Thomas Stuefe Assignee: Thomas Stuefe Priority: P4 Components: hotspot/runtime Original Fix: -1: N/A, JDK-8303823, N/A, -1 day(s) ago Backports and Forwardports: 21: Inherited 17: Inherited 11: Inherited 8: Inherited ---------------------------------------------------------------------------------------------------- 139 issues shown.
