ADDITIONAL SYSTEM INFORMATION :
Linux Mint 19.3 64bit, OpenJDK 14.0.1 GA

A DESCRIPTION OF THE PROBLEM :
I'm using JDK 14.0.1 GA and trying to create a small redistributable version of my application using the combination of jlink and jpackage.

In my application, I'm trying to validate some signatures with algorithm such as SHA256withECDSA, SHA384withECDSA and SHA512withECDSA. If I run my application with the standard JDK distribution, the application is working correctly, but if I run it with the result of jlink and jpackage, I get errors like

"SHA256withECDSA Signature not available"
"SHA384withECDSA Signature not available"

I've double-checked that libsunec.so is in place under the 'runtime/lib' folder, but I've seen that the SunEC provider isn't loaded at all during the start (just SUN and SunRSA are being loaded).

The jlink modules I'm using are:

java.desktop,java.smartcardio,java.management,java.sql,java.logging,java.net.http,java.xml.crypto,jdk.crypto.ec

and my jlink command is the following one:


jlink --strip-debug \
      --strip-native-commands \
      --bind-services \
      --no-header-files \
      --no-man-pages \
      --compress=2 \
      --module-path ${JAVA_HOME}/jmods \
      --add-modules java.desktop,java.smartcardio,java.management,java.sql,java.logging,java.net.http,java.xml.crypto,jdk.crypto.ec \
      --output jlink-runtime

REGRESSION : Last worked in version 14.0.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Write a program that verifies a file signed with EC Algorithms (e.g. SHA256withECDSA)

2. Optimize runtime with jlink

3. Create a package version with jpackage

4. Run application

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The Signature verification should work
ACTUAL -
Elliptic Curves algorithm aren't available at runtime. SunEC isn't loaded
