Hi Manas,

 

Can you please give your complete Soot command line or configuration options?

 

Best regards,

  Steven

Betreff: Re: [Soot-list] Analyzing rt.jar

 

Hello all

 

While analyzing rt.jar with custom entry points (as given in the soot wiki), I am getting different errors. For some methods, the analysis is successful (e.g., Object.equals); for some of them, I am getting “active body not found error (e.g., PrintStream.print) on using “getActiveBody” on those methods. Using “retrieveActiveBody” doesn’t help either; it throws errors like “This operation requires resolving level BODIES but java.io.PrintStream is at resolving level SIGNATURES”.

 

Any suggestions? The jdk version is 7.

 

Regards,

Manas

The Coffi frontend is not able to process the recent JDKs. You should use the default ASM one.

Hi Karim,

 

I am trying to analyze jdk8 (u45) on OS X. I am using the older “-coffi” frontend from soot-nightly-build. Further, I am keeping rt.jar in a separate directory and giving its address in the “-process-dir” option.

 

Regards,

Manas

Hello Manas,

 

Which JDK (version, OS, etc) are you analyzing? It seems it’s an OS X one as well. For some older version of Java on OS X, there are some additional jars you need to add on the soot classpath to be able to properly analyze rt.jar.

Hello all,

 

While analyzing rt.jar (with the -process-dir) option, I am getting the following error:

 

java.lang.RuntimeException: no superclass for java.lang.CharSequence                                                   │apple/laf/JRSUIConstants$Property.class

        at soot.SootClass.getSuperclass(SootClass.java:767)                                                            

…

 

If I use the released version of soot (soot-2.5.0), I get the following error:

 

java.lang.RuntimeException: Trying to create interface invoke expression for non-interface type: java.util.Map$Entry Us│apple/laf/JRSUIConstants$SegmentPosition.class

e JVirtualInvokeExpr or JSpecialInvokeExpr instead!                                                                    │apple/laf/JRSUIConstants$ScrollBarPart.class

        at soot.jimple.internal.JInterfaceInvokeExpr.<init>(JInterfaceInvokeExpr.java:46)                              │apple/laf/JRSUIConstants$PropertyEncoding.class

        at soot.jimple.Jimple.newInterfaceInvokeExpr(Jimple.java:433)

...

 

Can anyone suggest what may be wrong?

 

Regards,

Manas
