Steve Loughran commented on HADOOP-5254:
----------------------------------------
the root cause is in the stack trace, the base class impl of setXIncludeAware()
is (and this is sun code, so no cut and paste in apache):-
{code}
public void setXIncludeAware(final boolean state) {
throw new UnsupportedOperationException(
"This parser does not support specification \""
+ this.getClass().getPackage().getSpecificationTitle()
+ "\" version \""
+ this.getClass().getPackage().getSpecificationVersion()
+ "\""
);
}
{code}
Proposed: catch and l...@error, add some XML parser diags.
Incidentally, my JVM version is JRockit. I wonder if it is because it is pre
1.6u5, and that when Sun pushed out new features in that update, it included
XInclude awareness -as some versions of Java6 clearly do not have it
> Xinclude setup results in a stack trace
