For this you talk to the authors of alfresco CMS because they are the most likely people that get feedback about the bug.
I am using Windows Vista Home basic 32bit Edition on my laptop.
Model Lenovo y510.
Once I run my alfresco CMS tomcat (using Jdk1.6) it starts fine.
but once I tried to stop it (tomcat instance) it wont stop.
I tried to do through task manager end task, still it is not shutting down java.exe.
I tried to change compatibility mode for java.exe to XP. still it wont work.
I have to forcefully shutdown laptop.
any help on this?
