The following happens sometimes when running tests:

Comments

[Paul Libbrecht]

The attached pair of scripts seems to constantly raise the exception "Attempt to use a script that has been garbage collected.".
It combines a defined tag and an included script, quite a common situation, e.g. for Maven.
I could not find a way to reproduce the bug with only one of the two ingredients.

Invoke it with "java -jar target/fatJelly.jar blop.jelly".

PS: this comment was first done on JELLY-85... it might also be done on JELLY-148 where the patch was first prestented
PPS: we badly need to be able to link issues, that's a feature that "just needs to be enabled" in the jira.

I believe that this is fixed in HEAD.
