[jira] Created: (XALANJ-1988) Core dump: Sun Hotspot JVM 1.3.1_11b-02 optimizer core dumps optimizing a Xalan

Core dump: Sun Hotspot JVM 1.3.1_11b-02 optimizer core dumps optimizing a Xalan
-------------------------------------------------------------------------------

         Key: XALANJ-1988
         URL: http://nagoya.apache.org/jira/browse/XALANJ-1988
     Project: XalanJ2
        Type: Bug
  Components: transformation  
    Versions: 2.4Dx    
 Environment: Sun Sparc Workstation Netra-T4, Solaris 5.9, Sun Hotspot JVM 1.3.1_11-b02 (Optimization ON), BEA Weblogic 7.0 SP4 running Java Webapps (no JNI/native code), XalanJ2 (Implementation version 2.4.D1)
    Reporter: SAUVAGEAU Eric


I just added this issue to complete the problem reported by Manish.

In fact we are using XALAN this way :

    Transformer transformer = getTransformer(xslSource);
    transformer.setOutputProperty(OutputKeys.ENCODING, sEncoding);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    StreamResult mlResult = new StreamResult(baos);
    StreamSource xmlStreamSource = new StreamSource(xmlSource.toStringReader());
    transformer.transform(xmlStreamSource, mlResult);
  

the method getTransformer is like this :

 protected Transformer getTransformer(BDataXsl dataXsl) throws ExTransformerException
 {
   Transformer transformer = null;
   if (dataXsl != null) {
     // try to get it from cache
     String sKey = dataXsl.getKey();
     Templates translet = (Templates) _dataFactory.getCacheData(sKey);
     // do we have a transformer
     if (translet == null) {
      try {
	StreamSource xslStreamSource = new StreamSource(dataXsl.toStringReader());
	xslStreamSource.setSystemId(dataXsl.getFileName());

	translet = _transformerFactory.newTemplates(xslStreamSource);
	transformer = translet.newTransformer();
      }
      catch (TransformerConfigurationException ex) {
        // code omitted for clarity
      }
    }
    else {
     try {
	transformer = translet.newTransformer();
     }
     catch (TransformerConfigurationException ex) {
       // code omitted for clarity
     }
    }
   }
   // code omitted for clarity

My inderstanding is that Templates are thread safe and transformer are not but do you see any bad stuff in this code ?

Thanks in advance.

Henry Zongaro commented on XALANJ-1988:
---------------------------------------

Your usage of Templates and Transformer looks correct.

I'm not really sure why this pair of bug reports has been opened against Xalan-Java.  We don't have much information to go on.  I'm not aware of any bugs in Xalan-J that are liable to cause a JIT optimizer to crash.

SAUVAGEAU Eric commented on XALANJ-1988:
----------------------------------------

Thank you so much for your timely response.

I'm not really sure too this pair of bug reports has something to do with Xalan-Java.
I wanted to be sure our code is thread safe.
Now I can investigate with the HotSpot compiler.

Thank you very much.
