问题
I am getting a "javax.net.ssl.SSLException: Connection reset" for this piece of code
ReadableByteChannel rbc = Channels.newChannel(url.getInputStream());
but only when running under a Java 14 JRE built with jlink from Open JDK 14. The code executes just fine if I point to the full JDK. I suspect something is missing in the JRE, but what is it and why did jlink not copy the missing files accross? My jlink command based on jdeps is as follows:
"C:\Program Files\Java\jdk-14\bin\jlink.exe" --no-header-files --no-man-pages --compress=2 --strip-debug --add-modules java.base,java.datatransfer,java.desktop,java.logging,java.xml --output %AG14InstallDir%\jre_windows2
Am I missing a module in the jlink? Any ideas or suggestion on how to track this down?
After adding the debug as suggested, I get this output. What do I need to copy across to fix it?

Solved. Need to add jdk.crypto.cryptoki to the --add-modules list in jlink.
