Stale temporary files when using aspose excel converter

I got stale temporary files when using aspose excel converter.
It seems they are grows and deleted only when restarting application server.

Could you advice me what should I do to solve this issue? Thank you.

Hi,

Most of those temporary files may be created by Java’s Font related APIs. We cannot remove the generation of those temporary files entirely. However, in recent fixes we have made enhancements to reduce the count of temporary files, such as, we make sure that the temporary file for the same Font file will be created only once. Please try our latest fix (Aspose.Cells for Java v7.3.0.4) to see whether you can get better result.

Thank you.
