1# Test that the verifier does not stash methods incorrectly because they are being invoked with 2# the wrong opcode. 3# 4# When using invoke-interface on a method id that is not from an interface class, we should throw 5# an IncompatibleClassChangeError. FindInterfaceMethod assumes that the given type is an interface, 6# so we can construct a class hierarchy that would have a surprising result: 7# 8# interface I { 9# void a(); 10# } 11# 12# class B implements I { 13# // miranda method for a, or a implemented. 14# } 15# 16# class C extends B { 17# } 18# 19# Then calling invoke-interface C.a() will go wrong if there is no explicit check: a can't be found 20# in C, but in the interface table, so we will find an interface method and pass ICCE checks. 21# 22# If we do this before a correct invoke-virtual C.a(), we poison the dex cache with an incorrect 23# method. In this test, this is done in A (A < B, so processed first). The "real" call is in B. 24 25.class public LB21869691A; 26 27.super Ljava/lang/Object; 28 29.method public constructor <init>()V 30 .registers 1 31 invoke-direct {p0}, Ljava/lang/Object;-><init>()V 32 return-void 33.end method 34 35.method public run()V 36 .registers 3 37 new-instance v0, LB21869691C; 38 invoke-direct {v0}, LB21869691C;-><init>()V 39 invoke-virtual {v2, v0}, LB21869691A;->callinf(LB21869691C;)V 40 return-void 41.end method 42 43.method public callinf(LB21869691C;)V 44 .registers 2 45 invoke-interface {p1}, LB21869691C;->a()V 46 return-void 47.end method 48
