            Description

            The PDF attached to the forum (testICEpdf.pdf) is a one page document that has a content stream made up of for parts. For some reason each one of these stream fails to decompress correctly. When I process each part individually I get mixed results, where data is properly decompressed.

            I'll have to dig a bit deerper which is going to take some time. My best guess is that the stream has a token which is killing java.util.zip.InflaterInputStream but that's just a wild guess.

                Fix Version/s: 4.3.4

                Resolution: Fixed
                Added a catch for an IO error that occurs on a very small percentage of flatedecode encode streams. Basically the error can be eaten and the decoded stream returned.
