Hi,
After I switched to GWT 2.3 I suddenly have a custom annotation that fails
to compile with the Oracle javac....
I'm totally puzzled on how this can happen but maybe the GWT team have some
insight on what might me happening in GWT
that could cause this ? could this be caused by a misbehaving annotation
processors in GWT ?
The annotation in question is this one:
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface BuildEditorModelWith {
public String value();
public String datadir() default "test/data/editormodelbuilder";
Class<? extends PresenterFactory> presentations() default
StructuralPresentationFactory.class;
}
The bold line fails with an error that indicates that the
PresentationFactoryImpl.class is not compatible (but it is!)
jar.pretest:
[mkdir] Created dir:
/scm/vobs/srcSAG/mek/modules/editorweb/build/test-classes

com.swift.editor.shared.presenter.PresenterFactory>
[javac] abstract Class<? extends PresenterFactory> presentations()
default StructuralPresentationFactory.class;
[javac]
^
[javac] 1 error
When I change the line to use <?> to accept all classes everything is fine
(but I have to typecast in my tests where I use this annotation).
I really don't see how GWT 2.4 could cause this problem in my unit test
code, but the fact is: with GWT 2.3 in the classpath it works fine, with GWT
2.4 it no longer compiles.
I'm running JDK 1.6.0_22 (I can not upgrade it, enterprise bs) and it
happens on both SUN and Windows XP.
