> EasyMock/Mockito no longer works with Java 9 b148+
> --------------------------------------------------
>
> Key: SOLR-9893
> URL: https://issues.apache.org/jira/browse/SOLR-9893
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Tests
> Affects Versions: 6.x, master (7.0)
> Reporter: Uwe Schindler
> Priority: Critical
>
> EasyMock does not work anymore with latest Java 9, because it uses cglib
> behind that is trying to access a protected method inside the runtime using
> setAccessible. This is no longer allowed by Java 9.
> Actually this is really stupid. Instead of forcefully making the protected
> defineClass method available to the outside, it is much more correct to just
> subclass ClassLoader (like the Lucene expressions module does).
> I tried updating to easymock/mockito, but all that does not work, approx 25
> tests fail. The only way is to disable all Mocking tests in Java 9. The
> underlying issue in cglib is still not solved, master's code is here:
> https://github.com/cglib/cglib/blob/master/cglib/src/main/java/net/sf/cglib/core/ReflectUtils.java#L44-L62
> As we use an old version ock mockito (1.x), a fix is not expected to happen,
> although cglib might fix this!
> What should we do? This stupid issue prevents us from testing Java 9 with
> Solr completely!
