Problem

When attempting to access an HTTPS (SSL) resource, I receive a handshake_failure error.

Cause

The issue is most likely due to the limitation of Java cryptography capabilities.

Solution

A solution might be to download and deploy Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 8 (for Java 8).
Warning: It is possible that this may not be legal in your country. Be advised that you bare legal responsibility for activating unlimited strength Java cryptography capabilities, so you must have the legal right to use such cryptography (consult your export/import control counsel or attorney to determine the exact requirements for your jurisdiction).
To deploy it in Oxygen XML Editor, unpack the downloaded zip archive and move the two jar files (local_policy.jar and US_export_policy.jar) from UnlimitedJCEPolicyJDK8 to the following directory, overwriting existing files:
  • Windows - [OXYGEN_INSTALL_DIR]/jre/lib/security
  • Linux - [OXYGEN_INSTALL_DIR]/jre/lib/security
  • Mac OS X - [OXYGEN_INSTALL_DIR]/jre.bundle/Contents/Home/jre/lib/security
