Class DatatypeConverterImplInitiator

java.lang.Object

se.jiderhamn.classloader.leak.prevention.preinit.DatatypeConverterImplInitiator

All Implemented Interfaces:

PreClassLoaderInitiator

public class DatatypeConverterImplInitiator
extends Object
implements PreClassLoaderInitiator

DatatypeConverterImpl in the JAXB Reference Implementation shipped with JDK 1.6+ will keep a static reference (DatatypeConverterImpl) to a concrete subclass of DatatypeFactory, that is resolved when the class is loaded (which I believe happens if you have custom bindings that reference the static methods in DatatypeConverter). It seems that if for example you have a version of Xerces inside your application, the factory method may resolve org.apache.xerces.jaxp.datatype.DatatypeFactoryImpl as the implementation to use (rather than com.sun.org.apache.xerces.internal.jaxp.datatype.DatatypeFactoryImpl shipped with the JDK), which means there will a reference from DatatypeConverterImpl to your classloader.
