IssueTracker

I have an application which creates two DexClassLoaders, linked to another apps (with the same user id's, they are kind of plugins).

android.content.pm.ApplicationInfo appInfoSettings = this.getPackageManager().getApplicationInfo("xxx.yyy.zzz", PackageManager.GET_META_DATA);
DexClassLoader dclSettings = new DexClassLoader(appInfoSettings.sourceDir,getDir("dex", 0).getPath(),null,getClass().getClassLoader());

I can load classes from this one.

Then I do the same thing for another package. So far, so good.
But if I try to load a class from the second dex file, application crashes so bad, that it does, even if i try to do it from "expressions" panel in eclipse.

If I have one DexClassLoader it all works OK, no matter which package I choose.

Error reproduces on Android L. Nexus 5 and Genymotion emulator.
Android 4.4 and below works perfectly.

Part of the log after crash which I found interesting.
"xxx.yyy" - main package
"xxx.yyy.zzz||qqq" - child (loadable) packages.

I found this commit log:
https://android.googlesource.com/platform/art/+/a6b22c5be364a4ea926bfd2d0ea6169b22bdd10b%5E%5E!/ "Find OatDexFile by DexFile name and checksum, not just checksum"
Wonder if it correlates with my problem, I'm a java-only man.
