Please provide a reproducible usecase or sample source, thanks.
Comment 3 Peter Pis 2009-09-03 08:34:51 UTC 
Without requested information for long time - INVALID. We can't do anything in this case. Reporter, please add requested
information and reopen issue. Thanks in advance.

Just happened to me. 44 duplicates over the past 8½ years.

> We can't do anything in this case.

is certainly not true: javac could be patched to specify which type arguments were passed to `getDeclaredType` and which type was requested and what its expected type arguments would be, and `Utilities.resolveCapturedTypeInt` could be improved to be more defensive (if the actual bug is not obvious from inspection at that point). None of these changes require a reproduction case.

(A similar-seeming #166466 was fixed without an apparent test case BTW.)
