Exception using PDFBox

I was making some changes to try and improve performance and I started getting this exception:

[log4j][ServiceQueueSyncProcessThread: '0' for queue ProductsStmtService][2017-05-10 16:24:25,354] org.apache.pdfbox.pdmodel.font.FileSystemFontProvider ERROR Could not write to font cache

        at com.erac.servicequeue.sync.ServiceQueueSyncProcess.run(ServiceQueueSyncProcess.java:216)

The PDFGenerator.java:885 line is the line that sets up the HELVETICA font:

             try {
                    font = PDType1Font.HELVETICA;
                    fontBold = PDType1Font.HELVETICA_BOLD;
             } catch(Exception e) {
                    throw new ProductRequestException("Unable to find Fonts/arial.ttf", e);
             }

I wasn't getting this before, what would be causing pdfbox to try and write out a cache file?

Thank you,
Ray

The error is harmless, the cache won't be saved. How to avoid it? See this:

     private File getDiskCacheFile()
     {
         String path = System.getProperty("pdfbox.fontcache");
         if (path == null)
         {
             path = System.getProperty("user.home");
             if (path == null)
             {
                 path = System.getProperty("java.io.tmpdir");
             }
         }
         return new File(path, ".pdfbox.cache");
     }


So set one of these properties, and the problem is solved.
