Also note that Java 8 (Oracle and OpenJDK) uses native memory for class 
metadata (called Metaspace). PermGen no longer exists in these 
implementations, so you no longer have to guess an upper bound. You can 
still run out of memory, but Java 8 will never run out of PermGen.

See this blog post for more and a discussion of options to limit 
Metaspace, which is unlimited by default:
