Description Cagatay Kavukcuoglu CLA 2003-03-31 14:13:09 EST 
The VM throws a StackOverflowError during content assist after typing "double."
in the Java editor. I assume this happens for all primitive types though I only
tried double and int. The exception trace is in the attachment.

Comment 2 David Audel CLA 2003-04-01 05:21:24 EST 
I can not reproduce this problem in 2.1 release.

Cagatay - What is your version of eclipse ? Could you give me a specific test 
case ?
Comment 3 Cagatay Kavukcuoglu CLA 2003-04-01 21:12:41 EST 
I have 2.1 release installed. I had one other serious problem unrelated to this
bug after I reported this (A package private class in a project was not being
included in the Java model, thus a bunch of squigglies). I can't reproduce the
problem any more after purging all the JDT index files under .metadata and
rebuilding from scratch. I'll try some more and let you know if I manage to get
it broken again.
Comment 4 David Audel CLA 2003-04-03 08:24:33 EST 
I can not reproduce the problem, but it seems to appear with the following code 
(deducted from the stacktrace).

public class X {
  void foo(){
    ...
    new Object(){
      ...
      double.<cursor>
    };
  }
}

Cagatay - Could you look at the local history, to find the code which show the 
problem ?
Comment 5 Cagatay Kavukcuoglu CLA 2003-04-04 22:10:05 EST 
Unfortunately I'm hitting myself on the head now for not saving the code that
exhibits the problem. It's not in my local history. Your guess is pretty close
though. I tried the scenario you outlined and could not reproduce the problem in
my workspace. I'll try to think a few more alternatives and see if anything
comes up.
Comment 6 David Audel CLA 2003-06-10 11:55:44 EDT 
I can reproduce the problem in 3.0M1 with the following test case.

public class X {
  void foo() {
    new Object() {
      void bar() {
        new Object() {};
        double.<cursor>
      }
    };
  }
}
