Your guess is as good as mine. The JDK development/maintenance operates independently of this project. If you're looking for a fix there you'll need to pursue it with Sun. > Parsed document is not fully initialized until getFirstChild() is called > ------------------------------------------------------------------------ > > Key: XERCESJ-1147 > URL: http://issues.apache.org/jira/browse/XERCESJ-1147 > Project: Xerces2-J > Issue Type: Bug > Components: DOM (Level 3 Core) > Affects Versions: 2.8.0 > Environment: java version "1.5.0_06" > Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05) > Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing) > Saxon: saxonb8-7j > Reporter: Libor Valenta > Assigned To: Michael Glavassevich > Fix For: 2.8.1 > > > I have problems with Xerces bundled with JDK 1.5 as well as Xerces-J 2.8.0, I > was usin XSLT 2.0 transformer Saxon 8.7 to access document produced by java > extension.
