Hello,
We are currently using XALAN 2.1.0. Every now and again we obtain the
following exception when trying to create a new Transformer using
newTransformer() method of TransformerFactoryImpl:
java.lang.ArrayIndexOutOfBoundsException
at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:1048)
at
org.apache.xalan.processor.TransformerFactoryImpl.newTemplates(TransformerFa
ctoryImpl.java:864)
at
org.apache.xalan.processor.TransformerFactoryImpl.newTransformer(Transformer
FactoryImpl.java:687)
It happens periodically and with different XSL files. I use a
StreamSource(File) in the call to newTransformer. The XSL files are fine
because it works and transforms 99% of the time.
For debugging I trapped the TransformerConfigurationException that this
exception is part of. I then read and output the XSL file as a test. This is
fine.
I also try to create a Transformer using some other test XSL. This is also
fine - so I'm assuming the factory object is OK.
I've placed the code in a synchronized block because I'm aware of
concurrency problems with TransformerFactoryImpl:
private TransformerFactory factory;
....
synchronized(this.factory) {
try {
//throw new TransformerConfigurationException("Test
Exception");
return this.factory.newTransformer(new
StreamSource(this.xslSourceFile));
} catch (TransformerConfigurationException tcex) {
//Error handling code described above
}
Has anyone experienced a similar problem?
I found a post on
http://www2.real-time.com/pipermail/cocoon-users/2001-January/009997.html
that describes a similar exception with Cocoon.
The guy seemed to state that he only had the problem with a multi CPU
machine. If he used 1 CPU - it worked every time.
However our platform has 1 CPU:
SUN Netra T1/105 1 UltraSPARC CPU 360 Hz 512 M
JDK 1.3.1-b24
XALAN 2.1.0
Any ideas?
Many thanks in advance
Mark
