Mockito throws NullPointer when creating a mock object
I have an integration test in which some set up is done using Guice. I'm using Mockito to mock some of the dependencies. This has worked fine for me until now. I needed to use PowerMock for some other dependency. Now Mockito is throwing a NullPointerException while loading one of its own classes: java.lang.ExceptionInInitializerError at org.mockito.internal.exceptions.stacktrace.ConditionalStackTraceFilter.<init>(ConditionalStackTraceFilter.java:17) at org.mockito.exceptions.base.MockitoException.filterStackTrace(MockitoException.java:30) at org.mockito.exceptions.base.MockitoException.<init>
