Alfred commented on PDFBOX-4869:
--------------------------------
I tested the exception.
Looks like "new BufferedInputStream(null)" does not throw any exception and the
first read attempt will throw IOException("Stream closed") .
So the original "fail fast" behavior is modified.
Is this ok?

> Issue Type: Improvement
> Components: Parsing, Text extraction
> Affects Versions: 2.0.20, 3.0.0 PDFBox
> Reporter: Alfred
> Priority: Major
> Labels: Optimization

> I am testing text extraction from PDF and profiling the execution.
> I found that the second biggest time consumer is the static code in
> Standard14Fonts that loads fonts from the pdf box jar.
> The culprit seems to be the direct use of the stream returned
> getResurceAsStream.
> That would be a ZipInputStream when using PDFBox as a jar.
> Using a buffered stream around it reduces the load time a lot.
