Unfortunately, the following fix doesn't work.
Platform.isDebugBuild() ? "-XX:-VerifyDependencies" : "",
It seems that ProcessTools.createJavaProcessBuilder doesn't allow empty string as an arg.

Would you mind something like:
Platform.isDebugBuild() ? "-XX:-VerifyDependencies" : "-XX:MaxMetaspaceSize=16m",
If you don't like it, I still prefer -XX:+IgnoreUnrecognizedVMOptions.
I've grepped under jdk/test finding that there are about 700+ tests using -XX:+IgnoreUnrecognizedVMOptions.
I didn't get the point why -XX:+IgnoreUnrecognizedVMOptions should be avoided for this case.
