Description

I inserted raw time reporting functions before and after PDFTextStripper.writeText, it looks like it takes quite long to writeText to a StringWriter (84045ms for a ~1M pdf file).
It looks like a 1.8.x issues (I can reproduce on 1.8.9 and 1.8.10, didn't test on other versions yet). When I switched to 2.0.0-SNAPSHOT, and the time improved dramatically to 532ms using the same code and for the same pdf file. What I changed in code was only one import to accommodate PDFTextStripper's package change in 2.0.0.
