Hi, First of all, thanks again for your input on the matter! The strange thing is that the problem stopped to occur the next business day, with no changes applied to the system, but a windows restart. The classpath is correct, and the application is running as a GUI app. The error started to occur suddenly on hundreds of computers, then dissapeared the next day :| So, untill a root cause if found or i can replicate the issue on testing env, i'm expecting it back with the same randomness.. And it has a really big impact in our business... P.S: i can gain acces to the production computers and obtain any neccesary data.. as far as i know, until now, is that there were some windows updates targeted for installation in that period of time. Thanks!

Hi, Thanks for your response! Any ideas of why the sudden occurence? Can windows updates affect this behaviour? Those are the only changes made on the system recently. Thanks!

@Lucian, the answer seems legit, the only question remaining: how can this occur and then suddenly dissapear the next business day? :-/ Note that the plugin is trying to print a receipt on a microsoft windows 7 environment.

Hi, Recently, we encountered some problems in production when users were trying to print invoices. We are using Jasper Reports plugin, version 4.1.1, embedded into Oracle POS aplication. The error starded to occur yesterday randomly, and dissapearred today, on store opening, after all the systems were restarted. No binaries were changed or other configuration on the client machines. If you have any tips on this matter that could help identify the root cause, i will highly appreciate them.. I would like to add that i looked into a lot of answers online and i am currently trying to replicate the issue on testing env.
