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.
