I found the non-permanent target will be collection by GC early with `-Xcomp`. using `-Xlog:gc` can found the reason is:
`GC(0) Pause Young (Concurrent Start) (CodeCache GC Threshold) 12M->2M(258M) 16.437ms`
so I add `-XX:ReservedCodeCacheSize=512m` to make sure the test PASSED. Please review again, thank you.
