I could not recreate these failures locally (tried running with a single CPU core but that didn't help). The attached jtr files contain the "java.nio.channels.ClosedChannelException" test failure.

The test source is at https://github.com/jakartaee/platform-tck/blob/10.0.x/src/com/sun/ts/tests/jpa/jpa22/datetime/Client.java#L152

I suspect that one of the following commits may be causing the failures:
