[jira] [Commented] (XALANJ-2376) TransformerFactory.newTransformer(source) returns null instead throwing an exception

    [ https://issues.apache.org/jira/browse/XALANJ-2376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18014456#comment-18014456 ] 

Joe Kesselman commented on XALANJ-2376:
---------------------------------------

I believe we considered putting a default ErrorListener on our TransformerFactoryImpl implementations. I don't recall the outcome of that discussion.

xsltc.trax.TransformerFactoryImpl  is its own default listener (just printing to System.err)

I'm not seeing a default in the xsltc SmartTranformerFactoryImpl

xalan.processor.TransformerFactoryImpl inherits its initialization behavior from the javax SAXTransformerFactory.

>          Issue Type: Bug
>          Components: transformation

> The following code:
> +++
>      System.out.println("TransformerFactory: " + tf);
>      Transformer t = tf.newTransformer(source);
>      System.out.println("Transformer: " + t + " Source: " + source);
>      t.transform(source, doc);
>      } catch (Exception ex) {
>        ex.printStackTrace();
>      }
> +++
> throws a null java.lang.NullPointerException with 2.7.0 (at t.transform(source, doc);) and a org.xml.sax.SAXParseException (at Transformer t = tf.newTransformer(source);) in 2.6.0
> The problem is located in src/org/apache/xalan/processor/TransformerFactoryImpl.java  m_errorListener is wrongly initialized to DefaultErrorHandler(false)
