--- Comment #10 from Christopher Schultz <ch...@christopherschultz.net> ---
Have a look at this page:
https://wiki.apache.org/tomcat/FAQ/KnownIssues#ImageIOIssues

Try going back up to Java 10 and wrapping your streaming-ImageIO uses in the
class shown in that wiki page and re-running. If the crashes stop, we can go
ahead and blame them on ImageIO, but really tcnative should not crash in this
scenario... I'd expect that you'd just get lots of IOExceptions instead. So
tcnative isn't doing its job under this circumstance.

(n.b.: http/2 does not require Java 9.)

Unfortunately, I don't have  win32 debugging environment available to me, so
I'm not able to turn the 0xe6fc9 offset into a meaningful line of code to
investigate. It's obviously somewhere in the tcnative implementation of
SSLSocket.handshake (or something it calls). That function has ~100 lines of
code in it, but I'm guessing it's crashing towards the beginning, probably on a
read.

Can you use a DEBUG build of tcnative to get a better crash report? I'm used to
seeing more of a stack trace in native crash dumps.
