[Soot-list] TamiFlex

[Eric Bodden]

Hi Jochen.

Thanks for your message. Just to let you know, TamiFlex has its own
mailing list, which you may want to sign up for:
http://groups.google.com/group/tamiflex-discuss

But about your problem...

Line 130 holds this code:

String agentJarDir = agentJarFilePath.substring(0,
agentJarFilePath.lastIndexOf(File.separator));

Normally this should not be able to fail because agentJarFilePath
should hold the path to your poa-1.1.jar, and therefore should contain
a File.separator token. I wonder if this is a Windows-related problem.
I always tested TamiFlex on Unix-based systems. Could you let me know
the exact command line that you are using?

Some applications generate classes at runtime or load them from
obscure locations. TamiFlex therefore writes to disk all classes that
the application loads (including generated ones) into a flat
directory. This allows you to then easier supply these classes to
tools like Soot. If not needed, you can disable the option using this
command line:

java -javaagent:poa-1.1.jar=dontDumpClasses,<yourOutDir>

In general, if you just type "java -javaagent:poa-1.1.jar" this will
show you all available options.
