Tres Finocchiaro commented on PDFBOX-2682:
------------------------------------------
Work on this issue has begun. From the Oracle engineers:
{quote}
During the printing the method {{CRendered.doImage()}} is called. At that point
we have the following native call stack:
{noformat}
customPixelsFromJava() in ImageSurfaceData.m
syncFromJavaPixels() in ImageSurfaceData.m
LockImage() in ImageSurfaceData.m
doImageCG() in QuartzRendere.m
doImage() in QuartzRendere.m
Java_sun_java2d_CRenderer_doImage
{noformat}
There are at least two problems in customPixelsFromJava():
1. It invokes {{getJNIEnv()}} from ThreadUtilities instead of usage the
corresponding input parameter. According to the design - {{getJNIEnv()}} should
be executed on AppKit thread, but all code related to printing should NOT run
on AppKit thread. So we get the following assert here - {{Cocoa AWT: Not
running on AppKit thread 0 when expected}}
2. The function call {{syncFromCustom()}} method via JNI. According to the
code, the Java method should be located at {{OSXOffScreenSurfaceData}} class.
We looked through the corresponding Java code, but didn't find anything related
to that method. It looks like the method is just absent. When we try to invoke
it via JNI, we experience the crash.
Most likely Java cannot recognize type of images embedded to pdf file and
treats their type as `custom' (see {{TYPE_CUSTOM}} in {{BufferedImage}}), but
the code intended for handling this case is NOT implemented.

Possibly off-topic, but I find this particurarly interesting as we've other
issues in our codebase crashed by specific BufferedImage types.

> EI recently tested upgrading the PDFBox version in my project from 1.8.8 to
