      Description

      I'm using Tika 1.7. I'm parsing an encrypted PDF document which raise an exception. So far, so good.

      My concern is that after that I have a new System property set sun.font.CFontManager.

      Code to reproduce the error:

      @Test
      public void testSystem() {
          Properties props = System.getProperties();
          assertThat(props.get("sun.font.fontmanager"), nullValue());
          try {
              tika().parseToString(new URL("https://github.com/elasticsearch/elasticsearch-mapper-attachments/raw/master/src/test/resources/org/elasticsearch/index/mapper/xcontent/encrypted.pdf"));
          } catch (Throwable e) {
          }
          assertThat(props.get("sun.font.fontmanager"), nullValue());
      }
      

      With Tika 1.7:

      With Tika 1.6:

      [2015-02-11 16:38:42,922][INFO ][org.apache.pdfbox.pdfparser.PDFParser] Document is encrypted
      

      Note also that it logs a lot of errors which was not the case in Tika 1.6.
