superDevMode not working with Vaadin 7.6.0

Hi,
As we updated our application with the Vaadin 7.6.0, we couldn't able to run the superDevMode. 
This was because of library conflicts in class path. We have used libs in our project that contained an older version of jdt compiler

Similar problem can be found here :
https://github.com/johndevs/gradle-vaadin-plugin/issues/63

I managed to fix the problem by importing the "vaain-client-compiler-deps-1.2.0.jar" into classpath of superDevMode Run configuration in eclipse. I also moved it up to the first position.

Eclipse->Runconfiguration -->SuperDevMode code server for Project -> classPath
-> add Jar "vaain-client-compiler-deps-1.2.0.jar"

This has fixed the problem for me.

Steps i followed are:
1) Adding <set-configuration-property name="devModeRedirectEnabled" value="true" /> in DBarDemoWidgetset.gwt.gwt.xml
2)Launch the code server with "org.vaadin.alump.distributionbar.demo.widgetset.DBarDemoWidgetset"
3)Launch application on tomcat
4)Open application http://localhost:8080/DistributionBarDemo/?superdevmode

Please let me know if i am missing anything.
I tried to run the demo application of 'distribution-bar'  i,e (dbbar-demo)

Below is the link of source code of the addon https://github.com/alump/VaadinDistributionBar

Any hints on this is greatly appreciated :-)
