Start of the translation import does nothing. There is an exception on the console:
Exception in thread "AWT-EventQueue-0" javax.xml.parsers.FactoryConfigurationError: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found
This patch includes the xerces osgi plugin. It seems the xerces library was no more in the classpath because of changes in non-swing parts of iDempiere.
This is tested and works for me. Please integrate into trunk.
