VM argument UseSerialGC was not allowed while launching the debuggee process due to classloader related issue (JDK-8313655). During the effort to improve the test's handling of the issue, it was observed that SerialGC doesn't cause any issue any more. This could possibly due to improved handling of ClassLoaderData or SerialGC. After extensively testing the argument in various platforms and for many iterations, it was decided to allow the argument here on.
