        Description

        Having class unloading off by default for CMS has been causing perm gen
        out-of-memory exceptions. It is often a surprise to users. It was originally set
        to off to reduce the remark pause time. With removal of perm gen the
        result of not doing class unloading for CMS can be the consumption of
        unreasonable amounts of native memory. Also with the remark phase being
        done in parallel know, there is less benefit to having it off.
