Review request for JDK-8141524: CompilerTest execution time dominated by Field.setAccessible

[Attila Szegedi]

Please review JDK-8141524 "CompilerTest execution time dominated by Field.setAccessible" at <http://cr.openjdk.java.net/~attila/8141524/webrev.jdk9> for <https://bugs.openjdk.java.net/browse/JDK-8141524>

Shaved off 29s (9s instead of 38s) from CompilerTest execution time. Given it’s executed twice in “ant test” (optimistic+pessimistic), this reduces “ant test" run time by a minute.

Thanks,
  Attila.
