[janino-dev] [jira] Created: (JANINO-124) Janino generates StringBuilder for concatenation all the time

Janino generates StringBuilder for concatenation all the time
-------------------------------------------------------------

                 Key: JANINO-124
                 URL: http://jira.codehaus.org/browse/JANINO-124
             Project: Janino
          Issue Type: Bug
    Affects Versions: 2.5.14, 2.5.13, 2.5.12
         Environment: Java 5/6 for compilaction, Java 1.4 or less for execution
            Reporter: Brad Koehn
            Assignee: Arno Unkrig
         Attachments: UnitCompiler.java

There's no way to compile classes with Janino under Java 5/6 and run them under 1.4, if String concatenation is used.

I attached an updated version of UnitCompiler that checks for a system property which allows users to override the StringBuilder/StringBuffer choice.
