I'm getting the following exception when opening a Java file:

The session data is:

eclipse.buildId=4.27.0.20230309-1200
java.version=17.0.6
java.vendor=Eclipse Adoptium
BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=en_CO
Framework arguments: -product org.eclipse.epp.package.jee.product -keyring /Users/any/.eclipse_keyring
Command-line arguments: -os macosx -ws cocoa -arch x86_64 -product org.eclipse.epp.package.jee.product -keyring /Users/any/.eclipse_keyring

Any idea about this?

Are you approaching this as a user? If so I think it is best reported to the LSP4E project.

If you are trying to resolve this problem as an Eclipse developer, this error means that most likely the language server has exited unexpectedly.

Regardless, some additional information is going to be needed to help further. I tried opening a Java file with Eclipse for JEE devs 2023-03 (which is the version you are using AFAICT) and it worked fine.

@jonahgraham thanks for the answer. I'm approaching this as a user. I will create a ticket as you mentioned.
