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
Does it also happen with Amazon Corretto? They are at 232 now.
Is my understanding correct that it happens without PDFBox now?
Maybe try some other operations on that colorspace before doing
".toRGB()" so see if this avoids the error.
