[GitHub] [netbeans] sdedic opened a new pull request #2260: [NETBEANS-4123] PAC evaluator scripts runs just one at a time.
sdedic opened a new pull request #2260:
URL: https://github.com/apache/netbeans/pull/2260
NetBeans prefer the bundled-in `GraalVM:js` javascript engine for security reasons, but that engine cannot be used by multiple threads simultaneously. In fact, no javascript `ScriptEngine` probably can, since the shared toplevel scope is not likely to be thread-safe in a single-thread language.
The patch will simply prevent two threads from simultaneous execution in the same JS context; should not deadlock as the PAC evaluation cannot reach out to java classes.
