Research the impacts of the replacement of PermGen with Metaspace from JDK7 to JDK8

Metaspace Research

What is PermGen?

  • The Permanent Generation memory pool contains permanent class metadata and descriptors information when classes are loaded
    • PermGen space is always reserved for classes and items that are attached to them (i.e., static members)
  • PermGem space is contiguous in memory to the Java heap and have the same rounds of Garbage Collection but it is not part of the Java heap

What is Metaspace?

  • In JDK8, the PermGen space has been entirely replaced by Metaspace which is no longer contiguous to the Java heap and now exists in native memory

This process was documented by Ishan Sharma here: http://ishan.co/external-monitor-underscan and is a part of BashMatic library.
