APAR status

  • Closed as program error.

Error description

  • If you use Java method invocation, either through a service flow
with an external service that has a Java binding or through a
heritage service with a Java Integration that has the Translate
JavaBeans option enabled, and if the invoked Java implementation
 returns null, a NullPointerException is thrown and the
corresponding service task fails with an exception, which is
similar to the following exception:

Caused by: java.lang.NullPointerException
    at
com.lombardisoftware.component.javaconnector.worker.JavaConnecto
rWorker.bindOutput(JavaConnectorWorker.java:221)
    at
com.lombardisoftware.component.javaconnector.worker.JavaConnecto
rWorker.doJob(JavaConnectorWorker.java:129)
    at
com.lombardisoftware.component.common.workflow.ExecutionJob.doJo
b(ExecutionJob.java:549)

The exception might occur after a heritage service with a Java
integration that has the Translate JavaBeans option disabled is
converted to a service flow.


PRODUCTS AFFECTED
IBM Business Process Manager (BPM) Advanced
IBM BPM Standard
IBM BPM Express
IBM Business Automation Workflow

Local fix

  • Change the implementation of the Java method so that no null
values are returned.

Problem summary

  • The conversion of the return value of the Java method to a
Business Automation Workflow variable value fails if the value
is null.

Problem conclusion

  • A fix that correctly handles null values returned by a Java
implementation to an external service will be included in a
future version of Business Automation Workflow.

Temporary fix
