How to fix java.lang.ClassNotFoundException: com.ibm.websphere.ssl.protocol.SSLSocketFactory in eclipse

If you use IBM’s WebSphere plugin for eclipse you might have the problem that other plugins can’t establish an SSL connection anymore. The result is most times a ClassNotFoundException: com.ibm.websphere.ssl.protocol.SSLSocketFactory. This blog explains the reason behind the problem and gives a workaround to prevent that exception. Problem description When a component within eclipse (e.g. atlassian jira connector) tries to connect to an SSL socket a ClassNotFoundException: com.ibm.websphere.ssl.protocol.SSLSocketFactory is thrown. This exception is often the root cause of other exceptions.
