             Summary: Possible memory leak after calling decode filter
                 Key: PDFBOX-5199
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5199
             Project: PDFBox
          Issue Type: Bug
            Reporter: Tilman Hausherr


valerybokov noticed in PR#107 that filters are sometimes closed and sometimes not

IdentityFilter and CCITTFaxFilter extends Filter
IdentityFilter.encode(InputStream, OutputStream, COSDictionary). The InputStream will not be closed.
CCITTFaxFilter.encode(InputStream, OutputStream, COSDictionary). The InputStream will be closed.
The input parameter will not be closed if an exception is thrown.

My understanding is that the caller should close streams unless the javadoc tell something else. So I did search a bit, and found places in COSInputStream, COSStream and PDStream where this isn't done. Any close in filter should be removed.

I also searched for encode but there I found that the caller closes properly.
