Description
After appropriate testing, we need to turn on EnableMethodHandles and EnableInvokeDynamic by default.

This bug tracks that transition, and any regressions that may occur as a result.
Comments
EVALUATION The options EnableMethodHandles and AnonymousClasses are deprecated and will be removed in the future. EnableInvokeDynamic has changed from an experimental flag to a diagnostic flag and is the remaining option which turns on and off JSR 292 support (including method handles and anonymous classes). The default value for EnableInvokeDynamic is true for JDK 7 and later and false otherwise. EnableInvokeDynamic, and thus JSR 292 support in the VM, cannot be enabled when running with JDK 6 or earlier.
