Description:
Hello!

I get this error(it works for a few months and just after that this error appears):

03:56:40 [ERR][  GRTDispatcher]: exception in grt execute_task, continuing: Exception: Access denied for user 'root'@'localhost' (using password: NO)Launching SQL IDE

Is the second time that this happens to me, I re-installed MySql and after that it worked about two months, now I get it again... should I get another version of MySql Workbench?
I re-install it over and over again, there is other solution to my problem?

Thanks, 
Andra Luana

How to repeat:
I did the usual stuff, I created a few databases, I populated them and performed some adding and verifying some data using Java - Servlets, that's about all. 
Also I  work with JBoss and GlassFish, jetty and tomcat, but I don't think that is a problem because the are running on different ports... Also I installed WampServer, but it works on 8080, MySql works on 3306.

I don't know why this error appears, but this is the second time to me and I re-install it over and over again.

Please upgrade to 6.0.8 and check if the issue continues. Thanks.
