... 36 moreUsers did not have this problem with Jaspersoft® Studio release version 6.0.1. Using any 6.x version after that users were not able to publish their reports. When clicking on publish button the dialogue window never pops up, and users found the above error in the log file. They do not have problem retrieving report templates from JasperReports® Server repository and all their developers have this problem on their Windows machine in the following environment:
eclipse.buildId=unknown java.version=1.8.0_121 java.vendor=Oracle Corporation BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US Command-line arguments: -os win32 -ws win32 -arch x86_64 -data @noDefault
Noticing the error was related to eclipse, users had tried and further discovered that they cannot save modified report templates to workspace. Deleting workspace and restarting Jaspersoft Studio with a fresh workspace, even reinstalling Jaspersoft Studio 6.x, had no effect and problem persisted. Only after moving report template to another location outside workspace (to avoid eclipse managed workspace), users were able to save and publish the report.
Possible Solution
User had tried with newly released Jaspersoft Studio 7.1.0 and found out that this NullPointerException has been fixed. Although the origin of the problem is still undetermined, we suggest our users who might encounter similar odd behavior in their environment to try with latest version of Jaspersoft Studio product to see if it can fix this issue. As the last resort and work around, they may also try to edit and save report template in a location outside workspace to overcome this obstacle. In such situation, users should also file a case to report the problem for further investigation.
