However, It is not unusal to see the error “java.lang.OutOfMemoryError: PermGen space“if you are loading unusual number of classes. Gone are the days of OutOfMemory Errors due to PermGen space.With Java 8, there is NO PermGen. That’s right. So no more OutOfMemory Errors due to ...
PermGen is used to store classes, and is generally quite static in size. It's been removed as of Java 8. Setting Xms and Xmx Consider setting Xms and Xmx to the same value; this can decrease the time GC takes to occur since it will not attempt to reduce the heap on each...
Internedjava.lang.Stringobjects are also stored in the permanent generation. Thejava.lang.Stringclass maintains a pool of strings. When the intern method is invoked, the method checks the pool to see if an equivalent string is present. If so, it’s returned by the intern method; if not, ...
