This problem was resolved after installing Java version "1.5.0_07" on Jenkins machine to sync with the build machine that has the same java version, but unfortunatly we run into another problme! CVS plugin does not work with any java version below 1.6 as stated in the CVS plugin documentation "*Note:* This plugin uses Netbeans CVS Library which relies on Java 1.6 or above", so now we've to upgrade java version on all machines in order to use Jenkins!
