@mrserb added the reproducer and validated, that it works:

- *fastdebug* build: Before this change assertion is hit quickly, this will not be reported as a testfailure as the assertion handler displays a message and only blocks further execution of that thread, after the change no assertion is hit.
- *release* build: Before this change the JVM crashes and that is reported as a test failure, after the change the code runs through.

The test was run via:


CONF=windows-x86_64-server-release make test TEST="test/jdk/java/awt/Clipboard/ConcurrentClipboardAccessTest.java"
# and
CONF=windows-x86_64-server-fastdebug make test TEST="test/jdk/java/awt/Clipboard/ConcurrentClipboardAccessTest.java"
