Description
CDS regions require metaspace alignment; however, they are loaded with hardcoded allocation granularity (see filemap.cpp:1369ff). Since metaspace alignment is usually allocation granularity, this is only a problem if one modifies metaspace and changes the alignment. In that case, cds asserts at loading time.
