Start with the stack trace at OrderDetailActivity.java:526 and the referenced OrderDetailActivity_CF.getOrderTrackInfo() call, then compare behavior on the reported Android 5.0 and 5.1 devices with 4.x. Reproduce the IllegalAccessError using the referenced .apatch file; done means the affected versions no longer produce this failure.
