Cause

This is a known issue with WebSphere when SSL is enabled and using a JDK from the WebSphere Application Server (see references below).

When the IBM WebSphere Application Server starts up it sets the security property to the WebSphere default of com.ibm.websphere.ssl.protocol.SSLSocketFactory. Unfortunately the class com.ibm.websphere.ssl.protocol.SSLSocketFactory is but this class is not visible to the Java agent, thus the ClassNotFoundException is raised when trying to open a secured connection to Sealights' servers.
