+Workaround for ThreadTracker.checkLeak() failures on TeamCity.
+
+Currently TeamCity runs tests in classloader without boot.jar where IdeaForkJoinWorkerThreadFactory is defined. That
+makes ForkJoinPool.commonPool() silently ignores java.util.concurrent.ForkJoinPool.common.threadFactory
+(because of java.lang.ClassNotFoundException) option during factory initialization.
+
+Standard names for ForkJoinPool threads doesn't pass ThreadTracker.checkLeak() check and that ruins tests constantly.
+As it's allowed to reorder tests on TeamCity and any test can be first at some point, this patch should be applied at
+some common place.
