Parsing Errors about jitwatch HOT 6 CLOSED

Hi, the race condition between the various loggers in HotSpot is a known bug, filed as issue #3. I hope to speak to the HotSpot team about that.

Have you mounted any jars or class folders in the config? If nothing from the log could be classloaded that could explain the blank GUI. If not, could you email me your hotspot.log to [email protected] and I'll take a look?

Jars: of course.

RTFM :( I debugged through the code when I wondered why it expected XML tags and my log didn't contain any. I actually piped stdout to a file rather than using the generated hotspot.log. My bad, sorry! This is actually mentioned in the Wiki but maybe to make it even more fool-proof let the file open dialog filter for "hotspot.log" or show a warning if a different file name is selected.

No problem, thanks for trying it out! I'll put in some code to display a warning if the opened file isn't recognised as a hotspot log.

So, here's my suggestion:

FileChooser fc = new FileChooser();
fc.setTitle("Choose HotSpot log file");
fc.getExtensionFilters().addAll(
    new FileChooser.ExtensionFilter("HotSpot Log File", "hotspot.log"),
    new FileChooser.ExtensionFilter("All Files", "*")
);

That code works fine for Linux but there appears to be a bug in JavaFX on OSX Mavericks on 1.7.0_51 with the extension filter combo missing so you can't select anything other than the first filter. Have submitted a JIRA issue and will wait until response before committing this. Thanks :)

Added FilerChooser.ExtensionFilter except on OSX where there is a JavaFX bug with the filter combo not appearing. Got a response to my JIRA ticket that it won't be fixed in JavaFX2.2 (works in JavaFX8)
