             Summary: When runtime's JRE is changed to Java 8, both JDKs are in runtime classpath
                 Key: JBIDE-17437
                 URL: https://issues.jboss.org/browse/JBIDE-17437
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: server
    Affects Versions: 4.2.0.Beta2
         Environment: OS X 10.9 Mavericks
WildFly 8.0
JBDS 8.0.0.Beta2 B104
            Reporter: Martin Malina
            Assignee: Rob Stryker
             Fix For: 4.2.0.Beta3


I was playing a bit with the java 8 facet added in JBIDE-17126 and for that I had a WildFly 8 server set up with java 8. Then I changed the runtime to use java 7. Then back again to java 8. This resulted in an exception when starting the server:

I found this issue WFLY-3079 and it turns out that the reason is that when you changed a runtime's java from java 8 to java 7 and then back again to java 8, you end up with both JDKs in classpath. This should be fixed.

Note that this issue is most probably not exclusive to WildFly.
