 I am running OmegaT under Arch Linux with java-14-openjdk.

OmegaT does not claim compatibility with Java 14. We officially support only Java 8 and Java 11 for now.

Since this is not a bug (it's expected behavior) I have moved it to Feature Requests.

Upcoming Java17 in Sep. 2021 will be LTS and it would be good next target to be a base version.
Current Java 8 is supported until May 2026 at least, and Java 17 may be supported until Sep. 2026 at least.

Has @amake a planed timeline for next supported Java platform and migrations paths?

I haven't planned anything. The only thing I feel strongly about is that we should keep Java 8 support probably until EOL, although I am willing to reconsider if keeping Java 8 conflicts with some other very important goal.

The only thing standing in the way of support for new Java versions is that no one has done the work to fix the incompatibilities.

Groovy reflection error is not happened. IMHO, Groovy version is updated from OmegaT 5.3.0.

As of [50723f] OmegaT launches without error for me on Java 16, though I haven't tested it thoroughly.

I don't see much value to declaring explicit support for Java 14, as opposed to targeting Java 17 as Hiroshi suggested. So I will repurpose this ticket for Java 17.

The built-in Nashorn JavaScript engine was removed in Java 16 so that will be a blocker for this. [#1575] would address it.

  The built-in Nashorn JavaScript engine was removed in Java 16 so that some script will lost execution engine. Many scripts are written by Groovy but some in Javascript.
  we can see two js script in scripts folder.
  
  When we want to keep support js as OmegaT script, it will be also a blocker.

JAXB generation is also an issue for Java 17 compatibility.

OpenJDK 17 is out in 14, Sep., 2021 with color emoji support on macOS (and M1 mac).

Now it is good chance to evaluate OmegaT on Java17.
