Bug 90082 [1.5][generics] "New Class" wizard is not able to implement generic interfaces
In Eclipse 3.1 (JDT version I20050219-1500), the wizard for creating a new class seems unable to implement generic interfaces while specifying its argument. For example, implementing Comparable<Integer> is impossible; you have to first implement Comparable, and then correct the genearted stub for specifying its type argument. (in this example, replacing the Object argument of comparesTo by Integer.)

			fCurrEnclosingType= type;
			IPackageFragmentRoot enclosingRoot= JavaModelUtil.getPackageFragmentRoot(type);
			if (!enclosingRoot.equals(root)) {
				status.setWarning(NewWizardMessages.getString("NewTypeWizardPage.warning.EnclosingNotInSourceFolder")); 
			}
			return status;
		} catch (JavaModelException e) {
			status.setError(NewWizardMessages.getString("NewTypeWizardPage.error.EnclosingTypeNotExists")); 
			JavaPlugin.log(e);
			return status;
