Hi ,

I have jenkins installed 1.464 on tomcat webapps with JVM options as Xmx1024m -XX:MaxPermSize=512m in linux-x86-64 and have ant1.8.3 , maven3.0.3 versions installed automatically while configuring the Manage Jenkins>configure systems for config.xml and able to build jobs.
I have upgraded jenkins from 1.464 to 1.474 after 2 months and reloaded existed config.xml , all came up fine but while executing a ant/maven related existed build job , jenkins1.474 version recreating the Ant/Maven installations again without taking the existed one. no error logs coming.

Please suggest and help out to resolve the issue for this becuase this is blocking to not able to move forward with new upgrades of jenkins.
