[Soot-list] JavaToJimple : OutOfMemory

[Barthelemy Dagenais]

Hi,

I tried to convert a java source file into a jimple file but got an
OutOfMemoryException after ~two minutes (see below).

The java file is from Jython, a program from the DaCapo suite. When I try to
convert the corresponding class file into a jimple file, it takes only one
second. I also tried to convert several source files from Jython, but was unable 
to do so because of this exception. Any thoughts on how to proceed and why I'm 
getting this error?

I'm using soot version 2.2.4 (although -version says it's 2.2.3) and I'm able to 
convert java source files from smaller toy projects into jimple files.

Thanks,
Barthélémy



Here is the command I used to convert the class file PyFunction.class to jimple:

java -Xms512m -Xmx1512m
-cp
"$HOME/installation/soot/jasminclasses-2.2.4.jar:$HOME/installation/soot/polyglotclasses-1.3.4.jar:$HOME/installation/soot/sootclasses-2.2.4.jar:$HOME/installation/soot/java_cup.jar" 

soot.Main
-soot-class-path
"$HOME/installation/j2sdk1.4.2_16/jre/lib/rt.jar:$HOME/workspaces/runtime-PPA/Jython_2.2.1/bin/" 

-output-format jimple
-output-dir "$HOME/temp/ppabench/jythonjimple/" org.python.core.PyFunction

Output (with real path replaced by $HOME):

Here is the command I used to convert the source file PyFunction.java:

java -Xms512m -Xmx1512m
-cp

soot.Main
-soot-class-path

-src-prec java -output-format jimple
-output-dir "$HOME/temp/ppabench/jythonjimple/" org.python.core.PyFunction

Output:
