debugging - Mule Eclipse Debug Remote Mule Application Not breaking at breakpoints -

i using mule version 3.4.2. using eclipse ide(version: luna service release 2 (4.4.2)). installed anypoint studio plugin , able see pictorial view of flows. when trying debug through flows using remote mule debug, debugger not stopping @ specified breakpoint. whenever there exception though breaks @ random point.

i using default mule launcher configuration -m-dmule.debug.enable=true -m-dmule.debug.suspend=false -m-dmule.debug.port=6666

when start mule remotely do, $mule_home/mule -m-dmule.debug.enable=true -m-dmule.debug.suspend=false -m-dmule.debug.port=6666
