SurgicalDebugFilter class cast issue for zuul.debug.vip/host

[mind-kdas]

Getting ClassCast exception in SurgicalDebugFilter. I tried to set zuul.debug.host to some IP (XX.XX.XX.XX), IP & port (XX.XX.XX.XX:YYYY) and http://XX.XX.XX.XX:YYYY but still getting type cast error.

Caused by: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'http://localhost:9010' with class 'java.lang.String' to class 'java.net.URL'
at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.continueCastOnSAM(DefaultTypeTransformation.java:405) ~[groovy-2.4.10.jar!/:2.4.10]
at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.continueCastOnNumber(DefaultTypeTransformation.java:319) ~[groovy-2.4.10.jar!/:2.4.10]

zuul config:

zuul:
  debug:
    vip: http://localhost:9010
    host: http://localhost:9010

As per the code of SurgicalDebugFilter(https://github.com/Netflix/zuul/blob/v1.3.0/zuul-core/src/main/groovy/com/netflix/zuul/filters/SurgicalDebugFilter.groovy):

RequestContext.currentContext.routeHost = routeHost.get();
RequestContext.currentContext.routeVIP = routeVip.get();

This would result in error anyway since RequestContext.currentContext.routeHost is URL type but routeHost.get() would return string. So, the class cast exception seems fine. Let me know if I am using it wrongly or my understanding is incorrect.
