Subject Is IBM Right About Java?
Date Tue, 08 Feb 2011 16:27:25 GMT
Saw this statement on an IBM web site:

"Most JVMs grow towards the upper heap limit (-Xmx/-mx options) when
more memory is required, and do not return memory to the operating
system, even if the memory is no longer needed, until the JVM process

Is this true? If thought returning unneeded memory to the OS was what GC
is all about.
