a large amount of+~JF * *.tmp files is generated in the hard drive.

Hello，
Currently, when using the printing function, a large amount of+~JF * *.tmp files is generated in the hard drive.
After searching online, we found that it was caused by the use of the Font. createFont() method internally when we called your StiFontCollection. addResourceFont() method.
Font CreateFont() has another method that does not generate a large number of tmp files
Previously, tmp files were automatically cleaned up after the program ended, but now they are not automatically cleaned up
Could you please consider whether to optimize it

Hello,

Could you please send us a sample project that reproduces the issue?

Thank you.

Hello，
In a Linux environment，We call StiFontCollection.addResourceFont() method will cause this issue to stabilize.
It will write files to the/tmp folder, and when called multiple times, this folder will be full

Hello.

It seems that is bug of some Java versions, you can change Java version on your Linux environment to fix it.

[simon ren]

The problem is that you used the Font. createFont() method, which can also be directly searched online

[Vadim]

Hello.

This method load fonts from report resources, if you don't need this font you can remove it from report.

[simon ren]

This method has another usage that won't generate a large number of files. Can you consider optimizing it

[Vadim]

Hello.

We don't create .tmp files, it created by some Java versions, please change Java version to eliminate problem

[simon ren]

Hello，
From the figure, it can be seen that the file was generated in the method chain being called

There are two methods for createFont，
1.Font.createFont(Font.TRUETYPE_FONT, InputStream input);
2.Font.createFont(Font.TRUETYPE_FONT, new File(pathString));

The first one will cause the problem, and the second one will not. Can we change it to the second one

[Vadim]

Hello.

For our needs createFont with InputStream is necessary
