Start at ProxyServlet.java:516 and inspect how the request header or IP value reaches copyRequestHeader, using the reported JDK 1.8 stack trace as the initial clue. Reproduce the input "124:356:256:7889" if possible and determine the expected handling for the NumberFormatException and resulting NullPointerException.
