Tested on jdk 8 ubuntu 11.04
Testcase attached.

How to reproduce:
1 javac DisabledComponent.java
2 java DisabledComponent
Expected behavior:
List should be disabled(it works on windows)
Actual behavior:
List is enabled and is receiving events.

The problem exists in XComponentPeer.setEnable() it does not check container status.

SUGGESTED FIX http://hg.openjdk.java.net/jdk8/awt/jdk/rev/33c604bf074f

EVALUATION We should check container status before we set status of the component. This check was done during initialization before, it was moved to setEnabled() method.
