ASYM_ENCRYPT failure on Wildfly 10.1.0

Using ASYM_ENCRYPT on Wildfly 10.1.0 seems to be broken.

I am using the parameters for ASYM_ENCRYPT specified in http://www.jgroups.org/manual/index.html#Security

Note: running with SYM_ENCRYPT doesn't cause any issues and it works fine with my setup. Its only ASYM_ENCRYPT which is currently failing.

Note: running this on EAP fails in a similar manner.

Eg:
<protocol type="ASYM_ENCRYPT">
<property name="encrypt_entire_message">true</property>
<property name="sym_keylength">128</property>
<property name="sym_algorithm">AES/ECB/PKCS5Padding</property>
<property name="asym_keylength">512</property>
<property name="asym_algorithm">RSA</property>
</protocol>

If I run a single instance, then I don't see any problems appear in the logs. Its when I start a second instance that I start to see errors about unrecognised ciphers and timeouts.
