Description Whitney Sorenson CLA 2004-04-30 11:44:27 EDT 
Build 200404281424.

I was working on some code inside an inner class, and I cut/pasted into the main
class, and this error message came up in an error box. Once I closed the error
box, it kept reappearing, and I had to shut down Eclipse.

Could you please attach to this PR the source of the class you paste?
I need to investigate asap.

The class that caused the error

Here is a zip of the java file exactly as it was when the error occured. The
second time I was able to reproduce I simply had to paste the second set of    
	   }}}; below the private PropertyChangeListener stackListener = new
PropertyChangeListener() { line.
Comment 3 Olivier Thomann CLA 2004-04-30 12:39:06 EDT 
Reproduced. It seems to be a problem with positions and syntax errors in code.
Comment 4 Olivier Thomann CLA 2004-04-30 14:40:45 EDT 
We are in a case a field declaration has no declaration end and no declaration
source end.
There are two ways to fix it:
1) close the field declaration inside the updateOnClosingBrace(...)
2) close the field declaration inside the updatedFieldDeclaration()
Comment 5 Olivier Thomann CLA 2004-04-30 15:56:48 EDT 
I patch this problem.
David, could you please double-check my change in:
RecoveredField#updateOnClosingBrace(int, int)?

Thanks.
Comment 6 Olivier Thomann CLA 2004-04-30 15:58:21 EDT 
David, I added regression tests in ASTConverterTest2.
Comment 7 David Audel CLA 2004-05-04 05:37:04 EDT 
Fix seems good for me

Fixed.
