03:11:53 ERROR: SonarQube scanner exited with non-zero code: 1
03:11:54 Finished: FAILURE

Start by examining fr.cnes.icode.fortran90.rules.COMNAMEHomonymy.run at COMNAMEHomonymy.java:1477 and the call from Analyzer.stableCheck. Reproduce the SonarQube 6.7 analysis with the reported Java 8, plugin 2.0.1, and Fortran project setup, then verify that execution no longer ends with IndexOutOfBoundsException when the rule is disabled.
