<Swing Dev> [10] RFR JDK-6267105:UIDefaults.getUIError dumps error message to System.err and also throws Error.

[Shashidhara Veerabhadraiah]

Hi All,
	Please review the code bug fix for JDK-6267105:UIDefaults.getUIError dumps error message to System.err and also throws Error.

Issue:
     Error message was getting dumped to the system.err even though the recovery actions were performed leading to unnecessary confusion regarding the actual behavior.

Fix:
    This fix removes the call which prints the message to the system.err and stores the message in the Error class. This same message can be retrieved after we catch the error and calling getMessage() of the Error class. Through catching the error, the user can perform necessary recovery actions without cluttering the system.err. This fix does not modifies the 'user effect' as the user would still get the same error as they were getting before this fix.

Test:
    Now the system.err does not get cluttered though we performed the necessary recovery actions. The error message string can be recovered by calling getMessage() if needed.
