#1271 Custom Export not working

[FS]

When trying to use the custom export function I seem to stumble into a bug that prevents me from using it. I'm using a modified version of Mark Schenk's export filter and call it via the command line. However, since a recent system/Java update, this does not work anymore.

Here's what happens:

• When exporting my usual .bib file (attached: Hippocampus.bib) via the command line interface, I get a NullPointerException (see below).

• When using the export functionality via the GUI, I get the same error. However, when I use a much smaller/subset .bib file (attached: min.bib), the export actually works perfectly fine.

• However, trying to export the small .bib file via the command line, again, results in the same NullPointerException.

Here are the error/system details:

Could you provide the command line used?

Of course, here you go:

jabref -n -i /home/../Hippocampus.bib -o output_file.html,filter_name
