8024176: [macosx] gc/metaspace/ClassMetaspaceSizeInJmapHeap.java failed since jdk8b105, hs25b47 Summary: The code for reading compressed klass pointers in the sa-agent on Mac used readCompOopAddress instead of readCompKlassAddress, this is wrong but has been hidden because compressed oops and compressed klasses has used the same base address in the past.
