Missing "import" doesn't always produce a compilation error in BPMN2 process

1. Unzip reproducer-rhdm700.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"
