Hi Frank,
Thanks for your reply!
Re Jangaroo version, here's what it says in my POM.xml:
<properties>
<jangaroo_version>0.8.3</jangaroo_version>
<jangaroo_libs_version>0.8.5</jangaroo_libs_version>
</properties>
The error occurs at two places in the code. In both cases, the error happens at a lines that contains the second argument of joo.classLoader.prepare() calls.
Let me know if you need any additional information.
Thanks again,
Mats
