Java code throws exception only when called in async thread

Description

I have some code that formats JSON into a pretty printed string.

This code works fine normally but when called from an asyc thread, it fails with an error in the thread.log. This only stopped working in some recent Lucee update, I believe it worked fine in 5.2. Stacktrace from thread.log:

variable [JSONENGINE] doesn't exist;variable [JSONENGINE] doesn't exist;lucee.runtime.exp.ExpressionException: variable [JSONENGINE] doesn't exist

The regression starts from 5.3.5.26-SNAPSHOT onwards. It works fine until 5.3.5.25-SNAPSHOT. Might be related to .

I've checked this ticket and confirmed the issue happened while we using async thread. I think, maybe this is an expected error. will confirm about this issue.
