482755 - Java applets can hold onto uploaded files after they've been closed

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.7) Gecko/2009021906 Firefox/3.0.7

Firefox should be ensuring that an applet gives up whatever locks it's got on any files when it's shut down.  If an applet gets a lock on a file, and then the tab is closed, Firefox appears to keep those locks around.  The only two ways to resolve this are to either shut down Firefox entirely or use the Terminal to directly rm the file in question (assuming you were trying to delete it).


Reproducible: Always

Steps to Reproduce:
1. Upload a photo with the Facebook file upload applet
2. Close the tab
3. Move the photo to the Trash in OS X
4. Attempt to empty the Trash

Actual Results:  
Error indicating file is still in use.

Expected Results:  
File should have deleted successfully.

Do you have another Tab with a Java applet open ?
Firefox can only tell the plugin to shutdown but if it rejects to do that, it would be a plugin bug.
Does that work in Safari ?

Comment 2

[Bob Aman]

Nope, just the one tab.

Comment 3

[Matthias Versen [:Matti]]

Can you reproduce the error with Safari ?

Firefox doesn't do anything with the file, the Plugin itself opens the file and must release it. If the plugin itself doesn't do that it should be closed if the plugin gets unloaded. That should happen if the tab gets closed and Firefox sends a "Please go away" message to the plugin. It would be a plugin "bug" if the plugin refuses to quit. The sun JRE on windows is refusing to shutdown and the reason why Sun is doing that this (refusing to unload) is AFAIK that loading the Java plugin/JVM is very slow to load.

Interesting.  Yeah, Safari has the same problem, so it's the plugin's fault.

Is there a fix other than to complain to the facebook people?

Comment 5

[Matthias Versen [:Matti]]

I don't know much about Java applets and if it's just a missing "release resource" in the applet itself  which could be solved by Facebook or if this is a general Java plugin/JVM issue which can be only fixed by Sun or apple (isn't the Java JVM from apple on OS X ?)
