I found it ;) (some grey hair further)
the bug is in the method: ClassRenamer.endVisit(CssSelector x, Context
ctx), in this line:
actualReplacements.put(method, obfuscatedClassName);
Because of the reuse of the parent class HasOuterContainerStyle, the method
variable is the same when using an @Import that also extends from
HasOuterContainerStyle such that it overrides any existing OuterContainer
style in the above actualReplacements.
Example in my case I have:
> public interface SubscribeStyle extends CssResource,
> HasOuterContainerStyle {
> }
>
> public interface SubscribeResources extends ClientBundle {
> @Import(LinkButtonStyle.class)
> SubscribeStyle style();
> }
>
> @ImportedWithPrefix("LinkButton")
> public interface LinkButtonStyle extends CssResource,
> HasOuterContainerStyle {
> }
> Subscribe.css:
> .OuterContainer .LinkButton-OuterContainer {
> float: right;
> }
Note how both SubscribeStyle and LinkButtonStyle extend
HasOuterContainerStyle which will result LinkButton-OuterContainer style
overriding the original SubscribeStyle-OuterContainer style.
This happens when the imports are being processed in the method:
ClassRenamer.endVisit(CssSelector
x, Context ctx)
It will find the LinkButton-OuterContainer and will store this in the map:
actualReplacements:
actualReplacements.put(method, obfuscatedClassName)
Because the method used as key, is actually the same as that of
SubscribeStyle-OuterContainer,
it will override this latter one.
Note: the method is: HasOuterContainerStyle.outerContainer()..
Solution: ensure the key method in the map is unique under these
circumstances..
But I am not sure how, as it's an interface method and changing the key
might have too big of an impact on other code... The signature:
private final Map<JMethod, String> actualReplacements = new
IdentityHashMap<JMethod, String>();
Maybe it could be wrapped by a wrapper class that holds the orginal JMethod
with an identity that equals that of the JMethod and import prefix.
Something like this:
class JMethodHolder {
private JMethod method;
private String prefix;
.. constructors..
...hashCode and equals containing method and prefix..
}
I have put it in the issue tracker under nr:
