Create a hash table and access mutex to cache romClass to ramClass mappings from exceptiondescribe.c:findJ9ClassForROMClass. This saves time iterating over multiple class loaders to find a ram class. Entries will be deleted when a class is unloaded or redefined. Signed-off-by: Theresa Mammarella <[email protected]>
