# Test that the verifier does not stash methods incorrectly because they are being invoked with # the wrong opcode. # # When using invoke-interface on a method id that is not from an interface class, we should throw # an IncompatibleClassChangeError. FindInterfaceMethod assumes that the given type is an interface, # so we can construct a class hierarchy that would have a surprising result: # # interface I { # void a(); # } # # class B implements I { # // miranda method for a, or a implemented. # } # # class C extends B { # } # # Then calling invoke-interface C.a() will go wrong if there is no explicit check: a can't be found # in C, but in the interface table, so we will find an interface method and pass ICCE checks. # # If we do this before a correct invoke-virtual C.a(), we poison the dex cache with an incorrect # method. In this test, this is done in A (A < B, so processed first). The "real" call is in B. .class public LB21869691A; .super Ljava/lang/Object; .method public constructor <init>()V .registers 1 invoke-direct {p0}, Ljava/lang/Object;-><init>()V return-void .end method .method public run()V .registers 3 new-instance v0, LB21869691C; invoke-direct {v0}, LB21869691C;-><init>()V invoke-virtual {v2, v0}, LB21869691A;->callinf(LB21869691C;)V return-void .end method .method public callinf(LB21869691C;)V .registers 2 invoke-interface {p1}, LB21869691C;->a()V return-void .end method
