Support wildcard type parameters in GJ.

Reported by: moschny Owned by: moschny
Priority: normal Milestone: JPlater
Component: gjc Version: 1.07i
Severity: normal Keywords: Java5

Description

GJ doesn't support bound and unbound wildcard type parameters such as <? extends Tree>, <? super Tree> and <?> at all. This inhibits the usage of GJ and thus of JavaParty in a Java5 environment, because some of the library classes make use of those wildcard type params.

  • Version changed from 1.00 to 1.07i

The bugfix release 1.07i contains a hackish quick-fix: While reading class and method signatures from classfiles, wildcard type parameters are replaced in the following way: 

<? super C>    => <C>
<? extends C>  => <C>
<?>            => <Object>

Note: Maybe <? super A> should instead be replaced by <Object> ?
