Hi all,

could you please review this trivial fix removes compiler/types/correctness from problem list on all platform and problem list them only on solaris-sparcv9 due to 8225620[1]?

from JBS:

> The implementation in *load_extra_data()* has changed over the last few months (for JDK12/13) and may/should not manifest the problem any more. However, there might still be a potential problem (window) in *prepare_metadata()*, in the current JDK13 code base, where _PrepareExtraDataClosure_ will use the (now) fragile/raced (_SafepointSynchronize_) *safepoint_counter()*. The scenario would be that a safepoint has indeed started during *prepare_metadata()* but finishes after, without being detected.

> The test-case also uses the WhiteBox API to clean method data, via (_WhiteBox_) *clearMethodState()*. This would explain the (mal-) interaction with the previous implementation of *load_extra_data()*.
