Generic method in supertype not typed correctly in generated code

[alicederyn]

interface Foo<T> {
  T getBar();
}

@FreeBuilder
interface StringFoo extends Foo<String> {
  class Builder extends StringFoo_Builder {}
}

FreeBuilder generates invalid code for Main_StringFoo_Builder that references undefined type T instead of String.

Workaround: Redeclare the method in the subclass.

I can no longer reproduce this issue, even using the version of FreeBuilder that used to exhibit it, and I suspect it was caused by a bug in the version of Eclipse available at the time.
