Hi guys!
I am working on a project that was following the following JAR:
jasperreports-6.4.0.jar
jasperreports-fonts-6.0.0.jar
jasperreports-functions-6.8.0.jar
I removed these files and added the default files:
jasperreports-6.16.0.jar
jasperreports-fonts-6.16.0.jar
jasperreports-functions-6.16.0.jar
Now, when I generate a PDF report, I am creating multiple files with the .ttf extension inside Tomcat's "temp" folder, something like:
jr-font728979100838671575.ttf
jr-font1388394088188656820.ttf
jr-font2070626344255789384.ttf
jr-font2912536746518348255.ttf
jr-font4502507233541899064.ttf
It appears to be creating a file for each element of the report.
Why is this happening?
v6.16

Good Afternoon,
We are seeing this issue as well (lots of ttf files) in the temp Tomcat folder when using 6.16. They don't ge cleared down when the Tomcat service is stopped either. Any ideas what causes this or how we can ensure the ttf files are cleared down?
Cheers

Same for us at 6.15.0
As JR is running as part of a Spring Boot application we could not wait to clear files at shutdown as maybe some 1000 reports will be requested till shutdown.
For us this is crucial.
Cheers

I've run same tests on linux and found NO jr-font*.* files at all. Seems that they are not deleted on windows only?!
Can somebody confirm this observation?
Alex
Same is true for JasperStudio. A lot of jr-font8654562670586801975.ttf and jar_cache12072473203327495648.tmp files are created in Windows %tmp% folder. It seems this is done for every change/execution of a report, so the files sum up and don't ever get cleaned.
I have created a Pull request for fixing this issue:
