HeapSpaceStringConverter (Jenkins core 2.401.3 API)

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 XSTR-604.
Use this to avoid that (instead those strings will now be allocated to the heap space.)
