Even after JDK-8331999 we still see the javax/swing/plaf/basic/BasicDirectoryModel/LoaderThreadCount.java test fails more than 50% of the time in our CI tests. Currently we see these failures only on Windows and only in head.

A typical output would be:

Number of snapshots: 20
Number of snapshots where number of loader threads:
  = 1: 4
  = 2: 4
  > 2: 12
Duration: 17,467

The highest failure value I have seen was 13, but I only looked at 10 of our failed runs of the last weeks. Our tests run headless and with concurrency equal to the number of CPUs.
