I've got the same problem. JasperReports isn't running any more on Lucee 5.
That's the only reason why I can't use the new Lucee version.
Did you find a solution?
A few months ago I got the answer, that Lucee 5 has a plug OSGI
architecture which could have an impact on the java vm and the class
I receive the following error by generating a report on Lucee 5 (works fine
on Lucee 4.5):
Lucee 18.104.22.168-SNAPSHOT Error (net.sf.jasperreports.engine.JRException)
