I might have some time to look at
https://issues.apache.org/jira/browse/CXF-6610

before 3.1.5 gets released if not then we will do for 3.1.6

It should be a very basic update, say if an optional property 
"abortWhenThresholdIsReached" is set then a specific exception is 
thrown, and either JAXWS or JAXRS mappers can then map it to 503
