Hi,

As indicated by the error message, please set the -Xmx option (e.g. -Xmx1000m) to allocate larger heap space. 

Best,
Cheng

Soot has run out of the memory allocated to it by the Java VM.
To allocate more memory to Soot, use the -Xmx switch to Java.

Hi,

Sorry, I am not familiar with the example "callGraphs" you mentioned.
 But if your purpose is to obtain the call graph in Soot, here are some general steps:
1. Enable the -w option on the command line fed to soot.Main
 2. Extend the class soot.SceneTransformer and implement the method internalTransform
3. In the method internalTransform, use Scene.v().getCallGraph() to obtain the call graph.

For more details, you may refer to the survivor guide, especially chapters 4 and 7.

Best,
Cheng
