GWT compiler guru help need ...

Hi All,

I checked out the latest version (trunk) of GWT from git and tried to compile my current project with this state of GWT.

But during the compiling of the permutation I get an error message:

 Compiling 1 permutation

      Creating PermutationWorkerFactory instances

      Compiling permutation 0...

      [ERROR] An internal compiler exception occurred

com.google.gwt.dev.jjs.InternalCompilerException: Unexpected error during visit.

Shutting down PersistentUnitCache thread

What looks very strange for me: The class DefaultStyledText is not in my source path and it is also not final??

public class DefaultStyledText extends AbstractStyledText<AStyledDocument> {

    public DefaultStyledText(AStyledDocument document) {

        super(document);

    }

    @Override

    public String getPlainText() {

        return getValue().getPlainText();

    }

}

I have my own Object.java implementation. I simply added a implementation for the clone method:

    protected native Object clone() throws CloneNotSupportedException /*-{

        var r = {};

        // prevents to use same hash code

        @com.google.gwt.core.client.impl.Impl::getHashCode(Ljava/lang/Object;)(r);

        var o = this;

        for(var i in o){

            if(!(i in r)){

                r[i] = o[i];

            }

        }

        return r;

    }-*/;

Anybody of the GWT gurus here an idea???
