Description
Scenario:
- Have a process with a Groovy script task that statically references Camunda classes, such that they are resolved during script compilation (e.g. begin the script with import org.camunda.bpm.engine.delegate.BpmnError;)
- Application has no explicit module dependencies to either Camunda or Groovy
- Deploy script to Wildfly 10 distro
- Start process instance and execute script task (only tested with asynchronous execution via job executor, but issue probably applies to synchronous case as well)
- First execution of a script triggers script compilation
Current behavior:
Script compilation fails with the following exception:

Expected behavior:
Script compilation succeeds. It uses the globally (i.e. shared-engine) managed Groovy script engine. With that engine, it should be possible to reference engine classes by default without additional configuration by the user.
Reason of failure:
The global Groovy scripting engine uses the Groovy module's classloader for compilation, which of course does not have access to the engine classes.
Workaround:
Declare a module dependency from the process application to the Groovy module (importing services). This will resolve the Groovy scripting engine on process application level and apparently this then uses the PA classloader for compiling the script.
