[jira] Resolved: (XALANJ-2513) TransformerException:
NullPointerException with Java 1.6 on AIX

Henry Zongaro resolved XALANJ-2513.
-----------------------------------
Resolution: Invalid
Resolving as invalid, as it's caused by using a combination of classes from the Java run-time environment and the user's class path that is incompatible.
> 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
