Find IKVM replacement

[KevM]

It looks like post 1.17 that Tika will require Java 8. I believe IKVM v.Current has support for Java 8 but who knows how will this is going to work.

Investigate alternatives:

• Using the mono fork - https://github.com/mono/ikvm-fork
• Using JN Bridge

Hi,

Small question. Is it safe to say ... IKVM is dead .... long live the mono fork?

[KevM]

Is the mono fork in active development?

Last commit was a while ago. No actual releases of nugets. https://github.com/mono/ikvm-fork/commits/master

Could also be possible that there is just nothing to fix. The repository is way more actual then the latest IKVM version :-)

There is the IKVM8 Project, but no commits for the past year

But in the last few days, somebody started to attept to port IKVM to NET Core, seems quite interesting:

windward-studios/ikvm8#3

[MichaelPeter]

Actually Windward make progress on the. Netcore port windward-studios/ikvm8#3 Last update 14 days ago. On their website they say they also plan a Java 9 port. The are active on document generation. So Tika is maybe not so far off...

Also under active-ish development: https://github.com/jessielesbian/ikvm

I took a quick look at Jessie Lesbian's ikvm and Winward studio's port. My platform is currently Apple Silicon. So not ideal for this really but a good check of cross platform support of the implementations. Both are not ported to .Net core it seems. So... not really what we want.

.NET Core support. We now support .NET Core 3.1, .NET 5 and .NET 6. There are known bugs with Core which are not present in Framework. Specifically, System.Net.Socket is pretty broken on Linux. However, IKVM is useful on Core for many different scenarios...

@Hyldahl Thanks for the heads up. I tried out the pre-release and cannot get ikvmc.exe to work against any .jar files. I created an Issue and hopefully I can keep working on getting a Proof of Concept against this new version of IKVM working.

@KevM FYI I was able to get Tika working in .NET Core against the latest IKVM-Revived 8.2.0 for an internal project using the IKVMReference tag. You can find a (slightly outdated) sample harness here.
