java.lang.NoClassDefFoundError when switching to Nuix Engine engine-dist-win32-amd64-9.6.6.317 about nuix-java-engine-baseline HOT 3 CLOSED

Hello @chrishaupt this recently came up elsewhere and I have only recently learned of the solution, so I haven't yet had a chance to push up changes to reflect that solution.

This has to do with 9.6 using Java 11 and resolving particular crypto dependencies at run-time. Basically the JVM now needs to be passed this argument:

--add-exports=java.base/jdk.internal.loader=ALL-UNNAMED

I'll see if I can get this worked into the project here, until I do, I believe including that argument should resolve this issue.

Hi @JuicyDragon, this solves the problem! Thanks.

Another way I found yesterday was to add the bouncycastle dependencies (from the engine lib/non-fips directory) to the pom of my project. But I will stick to your way as it is more consise.

At run-time Nuix decides to go the FIPS or NON-FIPS route and dynamically loads some dependencies from the appropriate sub-directory. That dynamic dependency resolution seems to be the reason that argument is needed. While you might take another approach as you mentioned, I'm not sure if that has potential downsides. A senior member of the engine team told me that argument was the necessary magic to get this working so I'd say that's a good way to go 😄

Glad that worked for you. I'm exploring converting this project into a Gradle project due to some experience I've had to Gradle recently. Once I get there, the argument would be part of the build file and would be more of an after thought.
