Assessment failed: java.lang.RuntimeException: Could not generate DH keypair

I recently regenerated my DH params for neg9.org, and now assessing it via this tool fails with the following error:

 

Assessment failed: java.lang.RuntimeException: Could not generate DH keypair

 

The site appears to be working for other clients, any idea what's up? What kind of tests are conducted to validate EDH within SSL handshakes?

 

Thanks!

 

The test URL which triggers the failure:
