Description nothinbutnet 2005-11-16 22:03:35 UTC 
I was just editing a string in my .java file that I was constructing in this
manner "blah"+"blah"+"blah" when this error given at the end of this report
occured in an infinite loop.  I was still able to use the ide, but the
"Undexpected Exception" dialog kept popping up.   I was able to find a
workaround.  The error occured because I had redefined a variable.  Like this:

        String xml = "<"+ELEMENT_1+">"+"\n"+
                     "<"+ELEMENT_2+">"+fn2()+"</"+ELEMENT_2+">\n"+

        Iterator<String> i = list_.iterator();

        while (i) {
        
            
        }
/*        
    private List<String> sounds_ = null;
    private List<String> graphicWords_ = null;
    private List<String> sentences_ = null;
*/      
        String xml = xml + "  <!-- blah'"+fn6()+"' -->\n"+
                            "</"+ELEMENT_7+">";


I know the java code above is non-functional, I am only including it because the
error I received occured when I was just editing it to make if functional.  Here
was the workaround.  The like in question is:

        String xml = xml + "  <!-- blah'"+fn6()+"' -->\n"+
                            "</"+ELEMENT_7+">";

If I changed the above line to 

        xml = xml + "  <!-- blah'"+fn6()+"' -->\n"+
                            "</"+ELEMENT_7+">";

the exception infinite loop went away.


Good Luck!  and thanks for making a great IDE!

Comment 1 nothinbutnet 2005-11-16 22:09:02 UTC 
It just occured again, now I was able to get it to go away by terminating the
xml String definition with a semicolon like this. 


        String xml = "<"+ELEMENT_1+">"+"\n"+
                     "<"+ELEMENT_2+">"+fn2()+"</"+ELEMENT_2+">\n";

I reported both problems (this one and the one I created this issue for) when
the String xml definition had no semicolon.
