Running dex2oat on host computer

Question

I have compiled dex2oat on linux-x86_64 for linux-x86. I can run it just like a normal application. The background is, I have a tool which can generate dex codes and I want to perform some basic checks that dex2oat does. So it is not important for me to get an actual runnable file.

I do get the following output:

dex2oat I  4183  4183 art/dex2oat/dex2oat.cc:1239] out/host/linux-x86/bin/dex2oat --runtime-arg -Xms64m --runtime-arg -Xmx64m --image-classes=frameworks/base/preloaded-classes --dex-file=/home/marc/Apps/Example1.apk --dex-location=bla.apk --oat-file=bla.oat --image=out.art --base=0x60000000 --instruction-set=x86 --instruction-set-features=default --runtime-arg -Xrelocate --host --android-root=out/host/linux-x86 --include-patch-information

dex2oat F  4183  4183 art/runtime/runtime.cc:284]   | held mutexes= "abort lock" "mutator lock"(shared held)

Does anyone know what causes this error or did I supply the wrong arguments?

I have added a cout statement in the code and it turns out that the class being searched for is Ljava/lang/Object;
