I am using IReport 5.6.0 (though 5.0.0 has the same behavior) on Windows 10 64 bit machine.
I have tried to run The IReport with: jdk 1.6 64 bit, jre 1.7 64 bit, jre 1.7 32 bit (I have also jdk 1.8 installed but I am not using that with iReport as I now there is an incompatibility issues).
The environment starts normally - however if i try to push import or export buttons on datasource window - the iReport just exits and the window is closed - no error message is shown.
My colleagues with the same type of machines (W10 jre 1.7 32 bit) have no problem what so ever.
My question is - is there a way to get more information - as of why iReport exits what kind of exception is thrown etc... In other words how to debug this behavior?
From https://community.jaspersoft.com/project/ireport-designer
As of version 5.5.0, Jaspersoft Studio will be the official design client for JasperReports. iReport will remain as a supported product in maintenance-only mode until December 31, 2015
Which basically tells that you should switch to JasperSoft Studio
That said the best way for you to debug iReport is to check it's log that you can find in
C:\Users\[your user]\.ireport\[version of iReport]\var\log\messages.log
You can hunt and try to fix errors by yourself but don't expect JasperReport team to fixes these, since now they have moved to a new software.
