-------------------------------------
Hi [~julianhyde],
I have no further information about this. I'd suggest to ask on the Github
issue. We will disable the tests for now (using some {{assumeTrue("does not
work", Constants.JRE_IS_MINIMUM_JAVA9)}}). For Solr it's a bit more work as it
historically uses many mocking frameworks and all of these broke.
It is also not easy to fix this, as CGLIB is included in shaded form and
bundled with the mocking jars, so you cannot just replace cglib dependency at
one central place and all would work. You have to wait for updates of all those
mocking frameworks.
Not sure how to proceed :-(
> 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: Blocker
>
> 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 stone-aged version of 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!
