JakartaEE 10 support

[JSamir]

We are migrating our application to JakartaEE 10 and faced issues, it seems the client does not support running in JakartaEE 10 context.

Is there a plan to make it JEE10 compatible?

[dunedodo]

Currently we have not planned targeting JakartaEE.

[JSamir]

Since we were migrating our own application and therefore are familiar with the topic, we tried patching the ecs client ourselves. In general it works for us, although someone with knowledge about the internals of the client would need to have a look at few minor issues.

Would you accept a PR?

[dunedodo]

Yes, please. We will help review.

[JSamir]

We're currently building a release thus I will only have time for the PR in 1-2 weeks.

But one thing I wanted to mention already is that the changes we have made would make things work with JEE10, but JEE8 would not work (anymore). So you would either need to drop JEE8 support or somehow make both work.
