Instantiation of a XSLTC Translet may throw a VerifyError.

           Summary: Instantiation of a XSLTC Translet may throw a
                    VerifyError.
           Product: XalanJ2
           Version: 2.4
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: org.apache.xalan.xsltc
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: aspaans@smarttime.com


There's a test case (will be attached through a zip-file attached to this bug) 
whose XSL-file is compiled by the XSLTC correctly into a 
javax.xml.transform.Templates instance (internal Java Class), but whose 
instantiation into a javax.xml.transform.Transformor (internal Java Object) 
will throw a java.lang.VerifyError:

This is the reported exception:

java.lang.VerifyError: (class: test, method: POP_UP signature: 
(Lorg/apache/xalan/xsltc/DOM;Lorg/apache/xalan/xsltc/NodeIterator;Lorg/apache/xa
lan/xsltc/TransletOutputHandler;I)V) Expecting to find object/array on stack
	at java.lang.Class.newInstance0(Native Method)
	at java.lang.Class.newInstance(Class.java:232)

(TemplatesImpl.java:338)
	at com.probusiness.mvc.render.XSLRender.main(XSLRender.java:125)
Exception in thread "main" 

This exception/error can be surpressed by running the JVM with the parameter "-
Xverify:none". This will work in most cases, but then a NullPointer exception 
will be thrown instead at times (i have not test-case for this one):

ava.lang.NullPointerException

The runtime environment is:
Sun JDK 1.3.1 (tried 1.3.1_01, 1.3.1_02-b02 and 1.3.1_04-b02)
Xalan-J2 2.4.0
Xerces-2 2.1.0
