The problem occurs when camunda-webapp is started on WAS 8.5

The method org.camunda.bpm.application.impl.ServletProcessApplicationDeployer#onStartup gets a set with one entry as first parameter. The only element is the annotation @ProcessApplication itself. In the method, the annotation class is removed. After the removal, no entry is in the set.

This leads to an error in the line Class<?> paClass = c.iterator().next();
