(303/309) 1779 - SideKick infinite loop parsing properties file

SideKick can go into an infinite loop parsing certain property files. I've attached one that causes the issue reliably for me.

When I load the file, CPU usage shoots up (one core pegged at 100%, lots of memory allocations going on and subsequent gcs); if I try to modify the file, jEdit freezes.

Note that this is different from http://sourceforge.net/p/jedit/plugin-bugs/1629/; the example Matthieu lists there parses fine.

Hi Marcelo, what version of JavaSideKick do you have? I put in a release request for it earlier today, it parses and displays your attached properties file with no problems for me. My load average is 0.11 and jEdit CPU usage is around 1%. Can you compile the latest JavaSideKick source and see if that works for you?

Manager says SideKick 1.5, JavaSideKick 3.1.5; I'm not running the latest trunk, but I did just update the plugins today. If the new version fixes this, great.

Hello,

Had the same problem with one of my css file parsing. I desactivated the sidekick and no more cpu usage increase (with also disappearing cursor). I reenable sidekick now and will see if the problem has been solved today (I'm going to work on this css file).
SideKick 1.5 | jEdit 5.1.0 | Java Oracle (version 1.7) | Win 8.1 64bits
***Edit***
I'm not sure, my problem belongs to this ticket because it concerns Sidekick not JavaSidekick... :/

Jojaba, your issue is with a different plugin, the CSSSideKick which is part of XML Plugin, so you will need to submit a new bug report against that, and also please attach the file you are trying to parse as an attachment. It is most definitely a different issue.

Thanks Alan!
Seems, the error message I pasted is not in relation with the freezing...
I created a new ticket as recommanded : https://sourceforge.net/p/jedit/plugin-bugs/1784/
