1. Launch JMC 
2. JMC – File – Open 
3. File chooser is opened with file type "*" 
4. Select any .jfr extension file , so that JMC application can parse the same.

Expected : as per step 4.

Actual : "None of the .jfr extension files can be opened / selectable" 

Note: If we toggle the file chooser from "" to "ANY OTHER" and "ANY OTHER" to "" , Then we can select ".jfr" file. 

Note: This is only on Mac and its reported at https://bugs.eclipse.org/bugs/show_bug.cgi?id=540164
