Class HeapSpaceStringConverter

java.lang.Object
  com.thoughtworks.xstream.converters.basic.AbstractSingleValueConverter
      hudson.util.HeapSpaceStringConverter

All Implemented Interfaces:

com.thoughtworks.xstream.converters.ConverterMatcher, com.thoughtworks.xstream.converters.SingleValueConverter

public class HeapSpaceStringConverter
extends com.thoughtworks.xstream.converters.basic.AbstractSingleValueConverter

Up to XStream 1.3 the default StringConverter in XStream used String.intern(), which stressed the (rather limited) PermGen space with a large XML file. Since XStream 1.3 it use a WeakHashMap cache to always use the same String instances, but this has also major problems with a single long living XStream instance (as we have in Jenkins) See http://jira.codehaus.org/browse/XSTR-604

Use this to avoid that (instead those strings will now be allocated to the heap space.)
