The test case TestParallelRefProc fails on single core machines, since it expects that ParallelRefProcEnabled is always true if the ParallelGC is used:
test result: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: [-XX:+UseParallelGC] didn't set ParallelRefProcEnabled to true as expected
According to the code, ParallelRefProcEnabled is only enabled if there are more than 1 ParallelGCThreads. Ergonomics never configure more parallel GC threads than there are CPU cores.
