Why does SSL handshake give 'Could not generate DH keypair' exception?

Question

When I make an SSL connection with some IRC servers (but not others - presumably due to the server\'s preferred encryption method) I get the following exception:

Answer 1

It is possible that you have incorrect Maven dependencies. You must find these libraries in Maven dependency hierarchy:

bcprov-jdk14, bcpkix-jdk14, bcmail-jdk14

If you have these dependencies that is the error, and you should do this:

Add the dependency:

    org.bouncycastle
    bcmail-jdk15on
    1.59

Exclude these dependencies from the artifact that included the wrong dependencies, in my case it is:

    com.lowagie
    itext
    2.1.7
    
        
            org.bouncycastle
            bctsp-jdk14                
        
        
            bouncycastle
            bcprov-jdk14               
        
        
            bouncycastle
            bcmail-jdk14
