RFR: 8276819: javax/print/PrintServiceLookup/FlushCustomClassLoader.java fails to free

Thu Dec 9 22:53:41 UTC 2021

This is an attempt to make the FlushCustomClassLoader more stable. I cannot reproduce this bug so added some improvement blindly, based on assumption that the test may fail on the slow/overloaded system.

 * The attempt limitation was removed, but the test execution time decreased to 1 minute
 * For each attempt the generation of OOM was added to make sure that the GC was triggered
