Help wanted: compiling mockito with native-image

See original GitHub issue

I am trying to compile mockito with mock-maker-proxy with graalvm native image, and I got stuck with the plugin mechanism (At least the stacktrace point to that). (In preparation for having some mockito suppport in spring-native https://github.com/spring-projects-experimental/spring-native/issues/1063)

I know this maybe a little of topic, but having at least “some” mockito when running native tests made me get started with this.

What I’ve got so far is

some proxy config
some reflection config
basic compiler args

When I compile this example https://github.com/eiswind/native-mock-example

I get a NPE at:

     Caused by: java.lang.NullPointerException
       org.mockito.internal.configuration.plugins.Plugins.getStackTraceCleanerProvider(Plugins.java:26)
       org.mockito.internal.exceptions.stacktrace.StackTraceFilter.<clinit>(StackTraceFilter.java:20)
       com.oracle.svm.core.classinitialization.ClassInitializationInfo.invokeClassInitializer(ClassInitializationInfo.java:375)
       com.oracle.svm.core.classinitialization.ClassInitializationInfo.initialize(ClassInitializationInfo.java:295)

from which I would guess that registry itself is null, but that makes only little sense. I added some --initialize-at-runtime for the plugins package but that didn’t do it.

So for know I can only hope that this is something of interest and I really would appreciate some pointers what to try.

It works already: https://gist.github.com/raphw/e0f6864ddcad69630d839c2eebaad818

But it requires some prework. As far as I know, the Graal team is working on something to ease this.

I’ve added support for Mockito to the GraalVM reachability metadata and got the ProxyMockMaker to work, see here for more details.

The reachability metadata repo is a way to get non-compliant libraries to work nonetheless on GraalVM. Feel free to copy the GraalVM metadata files directly in the Mockito codebase (actually I would be very happy about that 😃).

What is the status of the other mock makers (particularly one which allows mocking of classes) on GraalVM?
