                + Arrays.toString(additionalVmOpts));

The problem is garbage at the end of the generated replay compilation file: [...] compile java/lang/invoke/MethodHandle <clinit> ()V -1 3 ethodHandle <clinit> ()V -1 3 The garbage comes from a file generated by an earlier run that was not yet deleted by the operating system (although deletion was requested by the test framework) and since the fix for JDK-8221738 we overwrite existing hs_err and replay files. We should truncate the file before overwriting. ILW = hs_err and replay files may contain garbage when overwriting existing file (regression), reproducible with replay compilation test, no workaround (but delete existing files) = MMM = P3

First failed with jdk-13-1028. Only on linux.
