This memory is used, in addition to the heap memory we specified before, for storing class meta data information. The default size will be unlimited – I tend to limit MaxMetaspaceSize with a . The default value is 64MB. The upper limit for this value will be approximately m on Solaris 7 and Solaris 8 SPARC platforms and m on Solaris and x86 platforms, minus overhead amounts.
