[Soot-list] Soot Body.getUnits() does not get ALL units

[Steven Arzt]

Hi Xinxin,

 

Can you provide a complete test case? From where did you read in your Jimple code?  Did you parse jimple files on disk or Java class files, or an Android APK?

 

Best regards,

  Steven

It sounds unreasonable to me too, but that is indeed the problem I encountered ... So I'm just wondering if there are some corner cases not handled by Soot or not ?

Hi Xinxin.

I am afraid that does not make much sense. By definition, the units of a body are the ones returned by getUnits(). This is a very strong invariant that should never be broken by Soot.

Cheers,
Eric
