title: weblogic.wsee.jaxws.spi.ClientInstanceInvocationHandler NullPointerException
body: <p>We got NPE</p>
  
  <pre><code>java.lang.NullPointerException
      at weblogic.wsee.jaxws.spi.ClientInstanceInvocationHandler.invoke(ClientInstanceInvocationHandler.java:172)
  </code></pre>
  
  <p>We use WebLogic wls12.2.1.3.0-190716 on jdk8u221</p>
  
  <p>This happens in one of our environments, all the other environments use the same setup and it works.
  Enabling DEBUG doesn't help, no additional logs at this point.
  We have log with the whole SOAP request prepared and then NPE. Request is correct - checked in other env.</p>
