8010722: assert: failed: heap size is too big for compressed oops
Summary: Use conservative assumptions of required alignment for the various garbage collector components into account when determining the maximum heap size that supports compressed oops. Using this conservative value avoids several circular dependencies in the calculation.

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.
