Java InaccessibleObjectException when running :Validate #618

Open McTrafaret opened 2 years ago

McTrafaret commented 2 years ago

I tried running the example from http://eclim.org/gettingstarted.html. Saving the file after System. didn't do anything. I then checked it once again with :Validate and it showed an error. In eclim logs i found the following:

java.lang.RuntimeException: java.lang.RuntimeException: java.lang.reflect.InaccessibleObjectException: Unable to make field protected java.lang.Object java.io.Reader.lock accessible: module java.base does not "opens java.io" to unnamed module @3c380bd8

I'm running Arch Linux 5.13.4-arch1-1. Eclipse was installed from AUR: https://aur.archlinux.org/packages/eclipse-java-bin/

Java version:

$ java --version
openjdk 16.0.1 2021-04-20
OpenJDK Runtime Environment (build 16.0.1+9)
OpenJDK 64-Bit Server VM (build 16.0.1+9, mixed mode)

And I'm running nvim can this be an issue?

$ nvim --version
NVIM v0.5.0

All other features seem to work fine.

UPD: tried on Vim 8.2 -- got the same

To quote the relevant error message:

java.lang.reflect.InaccessibleObjectException: Unable to make field protected java.lang.Object java.io.Reader.lock accessible: module java.base does not "opens java.io" to unnamed module

You should be able to fix that error by editing your eclipse.ini file and adding the following line:

--add-opens=java.base/java.io=ALL-UNNAMED

The location of your eclipse.ini file depends on what OS/platform you’re on, and where you have Eclipse installed.

On my macOS system, the eclipse.ini file is here:

/Applications/Eclipse Java.app/Contents/Eclipse/eclipse.ini
