Error when opening specific artist

[jdubso]

I get the error below for only one of thousands of artists. I tried changing the name on the folder and I still get the same error.

[gurutech]

Try updating Java. 1.7.0_17 is kinda old. I think they are up to _51 now, maybe higher....

[jdubso]

Stopped Tomcat, installed update to _51, cleared cache, started Tomcat

Same problem. Its really strange that its happening to just this folder.

[gurutech]

A couple other things to try:

Rename the folder, create a new folder with the name of the "old" folder, then move all your media/subfolders from the renamed folder to the new one. Delete the "old" folder.

After doing the above steps, run a full rescan on your media library.

Then test.
