Name collisions due to similarly obfuscated libraries

I'm currently working with a project that has several Android AAR library dependencies, independently built and obfuscated with R8. This setup initially caused crashes with NoSuchMethodErrors for the constructor of classes with obfuscated names like a.a.a.a.a.a. Apparently the obfuscation of multiple dependencies remapped different classes to the same name, only one of which was loaded into the application. Since the classes didn't have the same shape, the uses from one dependency required members that weren't there. I worked around the problem by directing R8 to -keep one of the classes that was mapped to the collided name according to mapping.txt.
