Subject Re: PropertyDescriptor: internal error while merging PDs: with jdk1.4
Date Fri, 13 Feb 2004 04:42:38 GMT

This error was as one of the classes in the project had a mismatch between
the field type and return for the getter.

What's interesting is that the error was not caused when run with jdk1.3.

thank you,
