<Swing Dev> [11][JDK-8197785]javax.accessibility.AccessibilityBundle will reload the ResourceBundle for every call to toDisplayString

[Krishna Addepalli]

Hi Phil

 

Thank you for the review.

 

I have checked the accessibility package, and found that contains is used with a Vector of AccessibleState objects in the file AccessibleStateset.

 

However in AccessibilityBundle, the table is used to store a set of values associated with a particular locale, and going by the context, I find little reason that using contains is intentional here. 

 

And regarding the testcase, the thought of making it headless crossed my mind while writing it, but I was not sure if just creating a Button is allowed in headless mode. 

Fortunately, I modified the testcase enough that, no swing widgets need to be created, and we can safely run the test in headless mode.

 

Here is the new webrev: http://cr.openjdk.java.net/~kaddepalli/8197785/webrev01/

 

Thanks,

Krishna

The fix is straightforward and I've seen this bug pattern before.
In fact there may even have been a sweep for uses of contains() to make sure it was as intended,
but if so it wasn't thorough enough.
But I'm wondering why the test extends Button and not JButton ?
I'm then further wondering if it could then be made headless .. ie no need to create or display a Frame ?

Hi All,

 

Please review a simple fix for JDK-8197785: https://bugs.openjdk.java.net/browse/JDK-8197785

Webrev:  HYPERLINK "http://cr.openjdk.java.net/%7Ekaddepalli/8197785/webrev00/"http://cr.openjdk.java.net/~kaddepalli/8197785/webrev00/

 

As the bug description suggests, AccessibleBundle.loadResourceBundle has the line "table.contains" which causes it to reload the resource bundle for each call.

Changing it to "table.containsKey" fixes the problem.

 

Thanks,

Krishna
