JR59039: AFTER YOU MIGRATE A BPEL APPLICATION FROM IBM BPM V8.0.1.3 TO V8.6, IT FAILS WITH A JAVA.LANG.VERIFYERROR

bpm.8600.cf2018.03.delta.repository

APAR status

• Closed as program error.

Error description

• When you execute BPEL applications that contain large XML
  documents and complex XSL stylesheets (for example, in mediation
   flows), you receive a java.lang.VerifyError with a stack trace
  similar to the following stack trace in the FFDC logs:

Local fix

• In your modules, use lazy parsing instead of eager parsing as
  the business object parsing mode.
  

Problem summary

• IBM BPM uses the XSLT processor from the XSLT4J library in BPEL
  processes and mediation flows. This XSLT processor can't handle
  large and complex XSL stylesheets, which causes a
  java.lang.VerifyError when you use a Java 8 runtime environment.
  
  PRODUCTS AFFECTED
  IBM Business Process Manager (BPM)
  

Problem conclusion

• An interim fix that uses the XSL transformation built into the
  IBM JDK that comes with WebSphere instead of the XSLT4J library
  is available for IBM BPM V8.6 CF2017.09 on Fix Central.
  

Temporary fix

• Not applicable
