solving java.lang.ClassFormatError: Field "has inconsistent hierarchy" in class

[vizlab]

Hi, guys:

This is the error message I got when I tried to run servlets.
How can I solve it? Thanks a lot.

All servlets or just that one? Have you tried recompiling it?

java.lang.ClassFormatError: Field "has inconsistent hierarchy" in
class myapp/web/servlets/ProjectListServlet has illegal signature "V"

Sounds like a corrupt .class file to me.

Unless there's a method called 'Field' in class
myapp.web.servlets.ProjectListServlet -- which I assume there isn't -- then
presumably the error message is complaining that some field is "declared" void.
Which is illegal/meaningless.
