The following test is failing in the JDK20 CI:

sun/java2d/Disposer/TestDisposerRace.java

Here's a snippet from the log file:

This test failure first happened in jdk-20+11-616-tier3 and the only
new changeset is:

JDK-8289208 Test DrawRotatedStringUsingRotatedFont.java occasionally crashes on MacOS

Since this appears to be a regression, I'm starting this bug off as a P2.
