What steps will reproduce the problem? 1. Write an empty test with a before class method
2. add as content of the beforeClass method this:
ClassPool cp = ClassPool.getDefault();
CtClass cc = cp.get("java.lang.String");
ClassFile cf = cc.getClassFile();
List methods = cf.getMethods();
for (MethodInfo m : methods) {
System.out.println(m.getName());
}
3. Add the javaagent to the VM argument : -javaagent:powermock-module-javaagent-1.6.0.jar, in the run classpath, set the javaagent jar first
4. Make sure to set the compliance of the project to 1.7 (using a JRE 7)
4. Launch test with the standard JUnit4 runner What is the expected output? What do you see instead? I expect the test to pass as with Java 6, instead I get:
java.lang.VerifyError: JVMVRFY012 stack shape inconsistent; class=TestPSC, method=beforeClass()V, pc=29

at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192) What version of the product are you using? On what operating system? JUnit 4.11, Powermock 1.6.0, javassist 3.18.2-GA Please provide any additional information below. Launching with a compliance 1.6 works perfectly fine, launching with 1.7 fails. I have also tried to add the option -XX:-UseSplitVerifier. And the javaagent jar is first in the classpath.

Any ideas?

Thank you!

The class is:

@Rule
public PowerMockRule rule = new PowerMockRule ();

static { PowerMockAgent .initializeIfNeeded();
}

@BeforeClass
public static void beforeClass() throws NotFoundException, CannotCompileException {
    ClassPool cp = ClassPool.getDefault();
    CtClass cc = cp.get("java.lang.String");
    ClassFile cf = cc.getClassFile();
    List<MethodInfo> methods = cf.getMethods();
    for (MethodInfo m : methods) {
        System.out.println(m.getName());
    }
}

@Test
public void test() throws Exception {
}
