Changeset: c689163a
Author: David Holmes <david.holmes at oracle.com>
Date: 2023-05-25 20:17:19 +0000
URL: https://git.openjdk.org/loom/commit/c689163a0c1d87c51695eb52a94f56f4fae3368c
Refactor of the Java code with the introduction of MonitorSupport.
The aim is to capture the different implementation options as `policy` objects
so the code just delegates to the current policy. This also aims at clarifying
the initialization issues and enabling use of fast-lock synchronization earlier
in the VM initialization sequence.

Fixes for virtual threads:
src/hotspot/share/prims/unsafe.cpp
- assert we don't get passed a virtual thread
src/hotspot/share/runtime/javaThread.cpp
- augment thread dumps to show virtual thread stacks for debugging
src/java.base/share/classes/java/lang/Monitor.java
- When dealing with virtual threads we have to pass the carrier to unparkMonitor
- When updating the status of virtual threads we have to update the carrier's status
- Fix doAwait() so that we always re-acquire the Monitor even if we throw an exception
- Expand logging
src/java.base/share/classes/java/lang/Thread.java
- Abort on lockStack access errors as we can't throw AIOOBE
src/java.base/share/classes/java/lang/VirtualThread.java
- expose carrierThread to Monitor class
