Crash at com.ibm.icu.impl.ICURWLock.a + 42(ICURWLock.java:42)

Question

I have an Android app that uses icu, however the stacktrace doesn't have any of my code in it, not to mention those aren't parts of icu that I use.

I have no idea how to even being to figure out this issue. Anyone have any ideas? I've never seen the crash myself, I just see it reported on fabric. I've used this library for several years without change, so I'm guessing it is something else that changed.

Fatal Exception: java.lang.AbstractMethodError: abstract method "void Hv.a(java.lang.String, java.io.FileDescriptor, java.io.PrintWriter, java.lang.String[])"
