Description Dave Latham CLA 2004-11-23 21:05:03 EST 
Eclipse Build: I200411230838
JVM: Sun 1.5.0-rc

I'm getting the following error.  I've managed to confuse myself while trying to
get rid of it about why it's happening, so am unsure what steps are necessary to
reproduce.  Hopefully a stack trace will be enough:

Let me know if I need to spend a while to isolate a reproducible case.
Comment 1 Olivier Thomann CLA 2004-11-23 21:33:41 EST 
Could you please provide the compilation unit that you were editing when this
happened?
Of course it would be great if you could isolate a reproducable test case. This
would definitely help us to fix it.
Comment 2 Dave Latham CLA 2004-11-23 21:59:37 EST 
Ok, I narrowed it down to a bit of code that I now realize is probably illegal
Generics usage:

public class ASTError
{
    private Map<String, Double>[][] fScoreTable = new Map[10];
}
Comment 3 Olivier Thomann CLA 2004-11-23 22:44:52 EST 
Even if the code is illegal, the converter should not blow up. I will investigate.
Comment 4 Olivier Thomann CLA 2004-11-24 12:14:44 EST 
Reproduced. I am working on it.
Comment 5 Olivier Thomann CLA 2004-11-24 17:17:23 EST 
Fixed and released in HEAD.
Regression tests added in ASTConverter15Test.test0076 and test0077.
Comment 6 Jerome Lanneluc CLA 2004-12-14 12:08:20 EST 
Verified (in I200412140800) that the test ensures that the source in comment #2
can be parsed and that an AST can be created from it.
