RFR: 8303740 JavaFX - Leak in Logging, Logging remembers last exception

Tue Mar 7 12:05:35 UTC 2023

When an exception is logged in JavaFX, then the exception is kept in a reference.
This way, always the last logged exception is retained.

This is a memory-leak.
This was done to write unit-tests to ensure certain error-cases are logged.

A simple fix is, to add a flag, to enable/disable retaining the exception.
