:JavaSearchContext never works

[isheff]

If, for instance, my cursor is on the S in System.out.println("Hello World"); in a basic demo file, and I run :JavaSearchContext, I get:

java.lang.RuntimeException: java.lang.IllegalArgumentException: File 'jar:file:///usr/lib/jvm/java-10-oracle/lib/jrt-fs.jar!java/lang/System.class' not found.
while executing command (port: 9091): -editor vim -command java_search -n "test-project" -f "src/main/java/com/isaacsheff/test/App.java" -o 154 -e utf-8 -l 6
Press ENTER or type command to continue

An analogous error appears for anything else in the standard libraries.

This is with Oracle JDK 10 on Ubuntu 18.04.

Can you run the command again, but with verbose?

:verbose JavaSearchContext

That should print the full stack trace which you can then post here.

:verbose JavaSearchContext results in:

I'm having the same issue for any built in types (e.g. Thread, AtomicBoolean etc).

Here's an output from :verbose JavaSearchContext when standing on currentThread of `Thread.currentThread()

It's obvious that it pulls up the file /Library/Java/JavaVirtualMachines/zulu-10.3+5. jdk/Contents/Home/lib/jrt-fs.jar and tries to get java/lang/Thread.class from that. It doesn't exist there though. That jar only has a handful classes (~66) from jdk/internal/jimage and jdk/internal/jrtfs.

Note: This works on a project using java8, so I think it's because of the changed structure layout of the JDK (since Java9) causing this.

Note2: In a Java10 project, the :JavaSearchContext command works fine for anything not in the JDK (i.e. dependencies and local classes all work).
