Based on the awesome feedback, I have been doing some offline development on EVars plug-in lately. I have added some basic documentation on wiki. Installation is now easy, let P2 do the work to install/update the plug-in (it's a struggle to host update-site with google code).
One of the most exciting feature (Which I can't stop talking about) is value based filtering. Now you can have all the powers of predicate expression, how about searching a map like map//key['@user.*']/.. to select entries matching regular expression user.* ? This update also includes support for relational operators so you can search exactly you want like this //value[count > n] .
I have uploaded OPath grammar for the language enthusiasts (left factored, left recursion free). One feedback was 'experiencing some unresponsive behavior for huge graphs' I have addressed that to some extent by integrating progress monitoring and asynchronous interpretation job.
Thanks for the feedback! Also, for those at EclipseCon have fun with your sessions!

Improve your debugging speed with EVars Eclipse plugin
Update: Added alternate link to screen-cast. Workaround to start plug-in
I have been debugging a lot lately which included open source libraries, closed source web-service engine and parts of closed source application server (WebLogic). During this painful debug-fest I felt a strong need for several features missing in Eclipse (NetBeans as well, for that matter) . Debugging closed applications is a pain beyond imagination, even with IDE integrated decompilers, it takes incredible amount of patience and time to debug.
To improve productivity (or prevent burnout), I jotted down a plugin to export/import live variables, filter variables view with a xpath like expressions etc. The plugin, called 'evars', features a small expression interpreter (similar to xpath) which can do a wonderful job of filtering variables on current stackframe. It also allows you to export variables to a file and reload them at a later point.
For the first time, I have attempted to create a screencast to explain its usefulness. You may watch it over here [10mb non-streaming, 1275x860], alternate link (open with your browser).
I have also created a beta release to see if it finds any interest which you can download it from here [JAR ~800kb, Jdk6] (Click here for Java 5 version) and drop it in dropins folder [Eclipse 3.4+]
If you find it interesting, please leave feedback here.
