Metaspace is the memory area for storing class metadata - internal JVM structures created while parsing .class
files.
Class metadata includes:
- Internal representation of Java classes
- Methods with their bytecode
- Field descriptors
- Constant pools
- Symbols
- Annotations
- etc.
-XX:MaxMetaspaceSize
is unlimited by default.
When -XX:+UseCompressedClassPointers
option is ON (default for heaps < 32G), classes are moved from Metaspace to the separate area called Compressed Class Space. This is to allow addressing VM class structures with 32-bit values instead of 64-bit.
So, Compressed Class Space contains internal representation of Java classes, while Metaspace holds all the rest metadata: methods, constant pools, annotations, etc.
The size of Compressed Class Space is limited by -XX:CompressedClassSpaceSize
, which is 1G by default. The maximum possible value of -XX:CompressedClassSpaceSize
is 3G.
Metaspace and Compressed Class Space are two disjoint areas. MetaspaceSize
does not affect the Compressed Class Space and vice versa.
