I get the following error
when I try to import a WSDL service (have tried PubChem and ChEBI):

"Could not read the WSDL definition from
https://pubchem.ncbi.nlm.nih.gov/pug_soap/pug_soap.cgi?wsdl:
javax.net.ssl.SSLException:java.lang.RuntimeException: Could not generate
DH keypair".

What I have tried:
- changed all Java local_policy and US_export_policy files with unlimited
versions. This did not work.

I am running Windows 10.

Possibly related to StackOverflow question: https://stackoverflow.com/questions/14253039/is-there-a-workaround-for-java-lang-runtimeexception-could-not-generate-dh-key/21617747

In [our investigation|https://gitter.im/apache/taverna?at=59f7250ff7299e8f534d9b20] we think
that you need to *remove* from taverna.bat/taverna.sh/taverna.vmoptions the equivalent of
lines:

{{
set ARGS=%ARGS% "-Dcom.sun.net.ssl.enableECC=false"
set ARGS=%ARGS% "-Djsse.enableSNIExtension=false"
}}

I can't find a log of why we added these properties in the first place; probably as a workaround
for an SSL bug in early JDK releases -- and should probably not be needed anymore with JDK8.
