    Compatibility between RDS 2.0.10 & Java SE 8 ?

    Yves Moriceau-Oracle

      Hi,

       

      I just upgraded from Java 1.7 to 1.8 (1.8.0_31) and my apexlistener (actually RDS 2.0.10) doesn't start anymore due to an exception error with the message below :

       

      D:\RDS2010>java.exe -jar ords.war

      Exception in thread "main" java.lang.

      UnsupportedClassVersionError: oracle/dbtool

      I read that some compatiblity issues may come with Java 8..

      Should I reinstall Java 7? is there any foreseen patch for RDS if it's a compatibility issue ? I also precise that I'm running my Apex environment in a standalone mode.

      Thanks for your feedback.

      Rgds,
