[jira] Created: (XALANJ-2513) TransformerException:
NullPointerException with Java 1.6 on AIX
TransformerException: NullPointerException with Java 1.6 on AIX
---------------------------------------------------------------
Key: XALANJ-2513
URL: https://issues.apache.org/jira/browse/XALANJ-2513
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in Xalan projects. Anybody can view the issue.)
Components: transformation, Xalan
Affects Versions: 2.7.1
Environment: AIX 5.2, IBM SDK Version 6, Xalan-J 2.7.1
Reporter: Robert Quan
Attempting to use trax to perform a transformation using IBM SDK Java 6 on AIX will result in a TransformerException: java.null.NullPointerException. If one was to use IBM Java 5, the transformation will run without issue.
The following details the data required to reproduce the issue:
Stylesheet (sort.xsl) - Note that the stylesheet will be precompiled into a translet in a jar called ipteXslTranslets.jar

[jira] Commented: (XALANJ-2513) TransformerException:
NullPointerException with Java 1.6 on AIX
Posted by "Henry Zongaro (JIRA)" <xa...@xml.apache.org>.
[ https://issues.apache.org/jira/browse/XALANJ-2513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12799357#action_12799357 ]
Henry Zongaro commented on XALANJ-2513:
---------------------------------------
Sorry - I probably should have realized what was going on sooner. IBM's Java 1.4.2 and Java 5.0 includes code derived from the Xalan-J interpreter and XSLTC, with some additional bug fixes and some other IBM-specific features. For historical reasons, all this is included in the IBM Java run-time environment with package names unchanged from the Apache versions of the code.
IBM's Java 6.0 no longer includes XSLTC, but instead includes a proprietary XSLT compiler. Code derived from the Xalan-J interpreter is still part of IBM's Java 6.0. So when you include XSLTC on your class path with IBM's Java 6.0, you end up with XSLTC picking up some classes from the boot class path (those that are included with the Java run-time) and others from your own class path. The versions of the classes are incompatible, and you end up with a NullPointerException.
This has been a long-standing problem with overriding a version of an XSLT processor that's included with the Java run-time. The way to work around it is to use the Endorsed Standards Override Mechanism to use your xalan.jar, serializer.jar, xml-apis.jar and xercesImpl.jar in preference to the version of the JAXP implementation that's included with your Java run-time. See [1] for more information.
I hope that helps.
