[Soot-list] java.lang.OutOfMemoryError when running with Dacapo Jython

[Marc Miltenberger]

Hi Lee,
well, it seems that Dacapo wants to convert the Callgraph to Dot and CSV
file and does this in-memory. This is not a good idea, since this graph in
particular seems to large. Try to optimize the Dacapo code that every part
of String gets written out to a file directly (without buiilding it in
memory before). Alternatively, give it more memory than 12 Gigs.

Look into the implementation of nz.ac.massey.soot.callgraph.
SootUtil.convertToDotAndCSV

Cheers,
Marc
