ConcurrentModificationException in JRXmlConstants

[seemarich]

 

hi,

We are using JasperReports 3.0

Occasionally, we are getting the following exception when generating a report. What could be the cause?

Thanks

Seema

This is probably a bug, please log it.  Make sure you include any information that would help us reproducing the problem.

Thanks, I have added the bug in the tracker here.

We noticed that the error occurs occasionally when two reports are generated using the same jrxml using Quartz jobs that fire at the same time.
