--- Comment #1 from Stefan Bodewig <bode...@apache.org> --- When I disabled the script tests for JDK 15+ I very quickly looked into using grall,js instead - but it seemed to involve quite a bit more than I was willing to chew on back then. Any helo is much appreciated. BSF seems to be more or less dead - it has become part of the Apache Commons Project but the last commit that changed anything but infrastructure stuff has happened more than five years ago. I believe, even when using graal.js the Ant ScriptRunner's "manager" should still be "javax" as this is the API we are using. AFAIU graal.js is the "language" you need to set. At least this is from a cursory glance at the migration guide you link to. We call "createEngine" here https://github.com/apache/ant/blob/master/src/main/org/apache/tools/ant/util/optional/JavaxScriptRunner.java#L193 -- You are receiving this mail because: You are the assignee for the bug.
