Powermock 1.6.3 with Javassist 3.18.2-GA produces a NoSuchMethodError

[Jayanth Avasarala]

I am using Powermock 1.6.3 with Javassist 3.18.2-GA, Mockito 1.10.19, JUnit 4.11 and JDK1.8. I did not write the tests or the test classes and therefore, I am not very familiar with these libraries. Did not have any problems building on JDK1.7. I have been assigned the task to uplift the application to JDK1.8 and that is when I encountered this error first. Also, the errors occur only in those test classes that mock classes that have static methods or have methods that call static methods (the test classes that use the PowerMockito.mockStatic() method). I have spent a lot of time working on the issue and I feel like I have reached a dead end. Any help will be much appreciated. Here is the stack trace of the error:

P.S. I have tried many different combinations of Javassist and Powermock and all of them have resulted in errors.

Hi,
You should probably try using the version of Javassist that Powermock uses.
Look in the pom.xml of Powermock, but I guess it's 3.20
