Semmle is an Eclipse plugin that allows "you to search your Java code by writing your own queries in .QL, an object-oriented query language", quite similar to SQL in fact.

In others words, you can search anything you want to know about your code by writing a simple .QL query and executing it. The results are displayed in a tree (see first screenshot).
Several charts can also be displayed.

I must admit that I never took the time to configure my Eclipse configuration (in Eclipse.ini file or with the launch command options).
Because I was bored of messages like "Eclipse is running out of memory...", I decided to find some information about the Eclipse configuration.

This is my eclipse.ini file:

-clean
-vmargs
-Xms40m
-Xmx512m
-XX:PermSize=128M
-XX:MaxPermSize=256M
-XX:NewRatio=3
-XX:+UseParallelGC

With this configuration, all OutOfMemory exceptions have gone, at least for the moment

Do not hesitate to share your experience.
Note that configuration depends on your usage of Eclipse...
