Howdy --
I'm unable to initialize the PDDocument class in PDFBox 2.0.17, as it
throws an ExceptionInInitializerError from inside ICC_Profile code on first
reference.
I'm using AdoptOpenJDK 11.0.4, but also (to my great surprise!) reproduced
the problem using OpenJDK 1.8.0_222-ga (albeit still using LCMS).
To reproduce the issue, one can pull the code out of
the org.apache.pdfbox.pdmodel.graphics.color.PDDeviceRGB initializer and
run it externally, as done below:
(import '[java.awt.color ColorSpace])
(let [cs (ColorSpace/getInstance ColorSpace/CS_sRGB),
black (float-array [0 0 0 0])]
(.toRGB cs black))
...which yields:
#error {
:cause nil
:via
[{:type java.lang.NullPointerException
:message nil
:at [java.awt.color.ICC_Profile intFromBigEndian "ICC_Profile.java"
1782]}]
:trace

...matching the relevant subset of the full stack trace, as seen below:

Any pointers?
