/*
 * This class should throw VerifyError because the StackMap for bytecode index
 * 9 (istore_2, line 60) is incorrect. The stack maps for bytecode indexes 9
 * and 18 (astore_2, line 70) do not match because 9 does not supply enough
 * locals to satisfy 18.
 *
 * The istore_2 bytecode at bytecode index 9 changes the type state,
 * preventing the stackmap mismatch.  But, if the incoming type state is used,
 * as required by JVM Spec 8, then the verifier will detected the stackmap
 * mismatch, and throw VerifyError.
