Error encountered while using Booster on the output of play-out agent

[Aritra Sengupta]

Hi All,

          I am trying to get the DaCapo 9.12 byte code transformed by TamiFlex play-out agent and bosster so that I can run static analysis on it.

          I am getting the following error  when I am trying to use booster  on the class files and log generated in the out directory for avrora small.

For first step I have used the comand:

java -javaagent:poa-2.0.1.jar -jar dacapo-9.12-bach.jar avrora -s small

http://code.google.com/p/tamiflex/wiki/DaCapoAndSoot

For the second step:

java -jar booster-2.0.1.jar -p cg reflection-log:out/refl.log -cp out:scratch -main-class Harness Harness

http://code.google.com/p/tamiflex/wiki/Booster

I am getting the following error.

Exception in thread "main" java.lang.RuntimeException: Line: 'Array.newInstance;java.lang.String[];java.util.Arrays.copyOf;2772;;'

at soot.Scene.addReflectionTraceClasses(Scene.java:1033)

Caused by: java.lang.RuntimeException: Unknown entry kind: Array.newInstance

at soot.Scene.addReflectionTraceClasses(Scene.java:1030)

This error was already there in the discussion list. in the poa-2.0.1.jar there is a file poa.properties. I have removed the following :

de.bodden.tamiflex.playout.transformation.array.ArrayNewInstanceTransformation \

de.bodden.tamiflex.playout.transformation.array.ArrayMultiNewInstanceTransformation \

and created  the jar back again. Even then the error still persists.

Could you please point me to the error in my steps.

Hi Aritra.

Please read the documentation about the configuration files. The file you need to alter is typically in your home directory, not in the JAR file:

https://code.google.com/p/tamiflex/wiki/ConfigurationFile says:
TamiFlex looks for those files first in the current working directory and, if no such file exists, also in ${HOME}/.tamiflex. If the respective file cannot be found there, a default file will be created. You can modify this file to your liking. The defaults below hold if this configuration file contains no value for the respective setting.

Hi Eric,

          I have modified the ${HOME}/.tamiflex/poa.properties and removed the first transformation to start with. Now I am getting the following error in Step 1:

sengupta@clouds transByte]$ java -javaagent:poa-2.0.1.jar -jar dacapo-9.12-bach.jar avrora -s small

FATAL ERROR in native method: processing of -javaagent failed

Aborted (core dumped)

Without removal of the first line in the file : de.bodden.tamiflex.playout.transformation.array.ArrayNewInstanceTransformation \

the class files and log are dumped properly for avrora. (I removed the line while trying to actually resolve the error that I was getting using the booster).

Strange...

Did you try giving it more memory?

Yes I am using the following command.

java -Xmx3072m -javaagent:poa-2.0.1.jar -jar dacapo-9.12-bach.jar avrora -s small

In the discussion list a similar issue was posted https://groups.google.com/d/msg/tamiflex-discuss/6q6ShId_TIw/AHKfp8pyG8MJ

which was possibly because of white space in the properties file. Not quite sure how to fix that if that's the case.
