Description
Originally filed as CR 7167657 under java_incidents : javawebstart category
FULL PRODUCT VERSION :
java version "1.6.0_32"
Java(TM) SE Runtime Environment (build 1.6.0_32-b05)
Java HotSpot(TM) Client VM (build 20.7-b02, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :
C:\Users\Ryan\Documents\NetBeansProjects\TestJava23XsltBug\dist>ver
Microsoft Windows [Version 6.1.7601]
A DESCRIPTION OF THE PROBLEM :
Java 1.6.0_32 fails to compile an XSLT which calls a static Java method with the error message mentioned below when the application is run via Java Web Start. The application executes correctly under 1.6.0_32 via command line. Note that the error message is mistaken regarding whether the extension function is state vs. non-static.
This is a regression as the application (executed via Java Web Start) behaves correctly in Java 1.6.0_31.
REGRESSION. Last worked in version 6u31
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the application included in the source code via Java Web Start. Observe the error message generated when running under 1.6.0_32 and observe the correct execution under 1.6.0_31.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The application is expected to execute correctly and to transform the XML document with the XSLT. The expected output to the Java Console window is below.
----------------------------------------------------
<html xmlns:ext="com.test.Test">
<body>one two</body>
</html>
ACTUAL -
Instead, the application reports an error to the Java Console Window when it compiles the XSLT.
ERROR MESSAGES/STACK TRACES THAT OCCUR :

CUSTOMER SUBMITTED WORKAROUND :
Work around is to direct our customers to fall-back to Java 1.6.0_31
