I'm trying to run a junit test.

i'm using: junit 4.10,
easymock 3.0,
powermock-core 1.4.10 (uses javassist 3.15.0-GA),
powermock-module-junit4 1.4.10,
powermock-api-easymock 1.4.10
with all the appropriate dependencies.
I have also try with powermock-core 1.5.5(javassist 3.18.0-GA)

(please note that only one more dependency ognl (uses javassist 3.7.ga)

test class:

@RunWith(PowerMockRunner.class) @PrepareForTest({MyClassToBeTested.class}) public class MyClassToBeTestedTest{ private MyClassToBeTested myClassToBeTested; @Before public void setUp() { // Partial mock with powermock myClassToBeTested = PowerMock.createPartialMock(MyClassToBeTested.class, "testMethod"); } @Test // IF I COMMENT THE @Test ANNOTATION AND public void testMethod() { // ALSO THE testMethod() THERE IS NO EXCEPTION } }

I know this is an old question, but I got exactly the same error recently after changing some other dependencies. It appears to be a bug in versions of javassist pre 3.18.2 (I note you were using 3.18.1).

I fixed it by upgrading Powermock to version 1.6.2 and explicitly adding a dependency on Javassist 3.19.0-GA.

This bug was fixed in Javassist 3.18.2-GA : https://issues.jboss.org/browse/JASSIST-223
