Calling Find Usages at a simple Maven project (non Java EE, it is a library), but this library is used at some Java EE projects, which some of them are opened.

Comment 13 _ tboudreau 2016-08-20 18:33:32 UTC

Created attachment 161731 [details]
stacktrace

Running find usages on a nested class generated from an annotation processor, where there are duplicate second-level nested class names, e.g.

class FooBuilder {
   static class WithBarAsString {
       static class WithBazAsInt { // <-----
       }
   }
   static class WithBarAsNumber {
       static class WithBazAsInt { // <-----
       }
   }
}

Guessing this confuses JPA refactoring?
