InnerException:

This error occurs after IKVM.NET update from 7.4.5196 to at least 8.0.5449 (the next one).
Using this version of IKVM.NET is critical for us because otherwise NHtmlUnit doesn' work with HTTPS in some cases due to 'Could not generate DH keypair' error at com.gargoylesoftware.htmlunit.WebClient.download(WebWindow requestingWindow, String target, WebRequest request, Boolean isHashJump, String description). As far as we can see, this is due to an obsolete Java version, that is, IKVM.NET 7.4.5196 is too old. (Indeed, IKVM.NET 8.0.5449 is more than a year old).
Could you please include the IKVM 8.0.5449 support?

Thanks in advance,
Regards, L.B.

@enderteszla Thanks for your patience! I'm working on this in #25. When it and #23 is completed, I'll push out a new package on NuGet. I'll let you know here as soon as it's done.

Excuse me whether has been solved? IKVM 8.1.5717.0 version, there is the problem. What should I do with?

[asbjornu]

@Skygrain: I'm sorry, but #23 is still not complete, which is what I need to do before we can get a new release out the door. That release will hopefully fix the problem.

NHtmlUnit 2.19.0 was released November 24th 2016 and should fix this. If not, please reopen.
