BPEL Validation Errors in NetBeans 5.5.1

I‘ve recently updated my production NetBeans 5.5 environment to NetBeans 5.5.1 and have been having some issues with BPEL modules.

If I create a BPEL module in NB 5.5, everything works as expected, however if I try to build the same codebase on NB 5.5.1, I get the following error.

Interestingly enough, I get the same problem with NB 6 M10

<target name="pre-dist"> 
09-Jul-2007 13:08:44  
org.netbeans.modules.bpel.project.anttasks.IDEValidateBPELProject 
loadAndValidateExistingBusinessProcess 
SEVERE: Validation has errors on /home/david/NetBeansProjects/EchoBPEL/src/EchoProcess.bpel

The following error occurred while executing this line:

java.lang.AbstractMethodError:

getSchemaSource()Ljavax/xml/transform/Source; BUILD FAILED (total time: 0 seconds)

Does anyone else have this problem? The workaround I have found at the moment is to comment out the BPEL validation code in the ant script (build-impl.xml line 155) as follows:

<target name="pre-dist"> 
        <!-- Empty placeholder for easier customization. -->
  
        <!-- You can override this target in the ../build.xml file. -->
        <mkdir dir="${build.dir}"/> 
        <!-- run the validation task here. -->
<!– 
        <BpelProjectValidate buildDirectory=”${basedir}/${build.dir}” 
        sourceDirectory=”${basedir}/${src.dir}” 
        projectClassPath=”${javac.classpath}” 
        buildDependentProjectDir=”${basedir}/${build.dir}/dependentProjectFiles” 
        classpathRef=”ant.task.classpath.validation”  
        allowBuildWithError=”${allow.build.with.error}”/>
