GraalVM PolyglotException when a runner class is used to run scenarios involving 2+ call-s before running a JS function

[staffier]

With v1.2.1.RC2, I'm running into a number of these errors:

org.graalvm.polyglot.PolyglotException: java.lang.AssertionError

• com.oracle.truffle.js.runtime.JavaScriptRealmBoundaryRootNode.execute(JavaScriptRealmBoundaryRootNode.java:75)

It appears as though a couple things are required to expose this issue:

1. Two (or more) call-s need to take place before any JS function is utilized
2. The test needs to be run using a runner class

It took a while to whittle things down, but the attached project is about as bare-bones as I could make it. If you use the runner class to test things out, one Scenario will pass and the other will fail. And if you bump the version down to 1.2.0, the issue vanishes.

this is related to the JS engine / graal issues that needs a big push of refactoring: #2003 (comment)

@staffier for this one also can you see if the latest develop branch works

[staffier]

Looks like this needs to be updated in KarateLexer.java & KarateParser.java:

ANTLR Tool version 4.9.2 used for code generation does not match the current runtime version 4.10.1

@staffier that's weird, can you do a maven clean. also if you are using an ANTLR plugin in IntelliJ please disable or uninstall it first

I changed it to 4.9.2 in the karate-core pom file and everything worked -- the test in question no longer fails when I run it with my runner. Nice!

okay, I'm going to mark this as duplicate of another issue and close, thanks ! anyway we will release an RC version soon so we can double check

this is a duplicate of #1883 which is fixed
