      1. Unzip reproducer-rhpam700.zip
      2. cd reproducer-class
      3. mvn clean install
      4. cd order-error-reproducer
      5. export MAVEN_OPTS="-XX:hashCode=0"
      6. mvn clean package
      7. Repeat step 6. You will see sometimes success, sometimes failure

      Note, with JDK 8, "-XX:hashCode=0" may be required to reproduce the issue constantly with this reproducer (The default hashCode=5 sometimes generates the same hashCode upon JVM restart so not good to check "different behaviour per test execution"). But this is not a fundamental factor of the issue. Users may add many BPMN2 files so they would hit this issue randomly even without "hashCode=0"

    Description

      When a kjar project has:

      • Process A has a correct import (e.g. "org.test.reproducer_class.App") and accesses to the class in its ScriptTask

      and

      • Process B misses the import and accesses to the class in its ScriptTask

      , kjar build results in sometimes success and sometimes failure. (depending on which process is compiled first, so depending on hashCode)

      Failure message is like this:

      [ERROR] Unable to build KieBaseModel:defaultKieBase
Process Compilation error : Process org.drools.bpmn2.Hello World(com.sample.bpmn.hello2)
	org/drools/bpmn2/Process_org$u46$drools$u46$bpmn2$u46$Hello_World353857208.java (9:398) : App cannot be resolved to a type
	org/drools/bpmn2/Process_org$u46$drools$u46$bpmn2$u46$Hello_World353857208.java (9:412) : App cannot be resolved to a type

          Bug - A problem that impairs or prevents the functions of the product. RHPAM-1211 Missing "import" doesn't always produce a compilation error in BPMN2 process

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
