Jigsaw b136 ServiceLoader Regression

[Richard Opalka]

Hi Jigsaw team,

    there is a regression in Jigsaw JDK9 build 136

causing ServiceLoader.iterator().next() to propagate

other error than ServiceConfigurationError, see below.

According to javadoc (java.util.ServiceLoader.iterator()):

" To write robust code it is only necessary to catch 
|ServiceConfigurationError| <cid:part1.33D07682.B45F1A26 at redhat.com> 
when using a service iterator."

Is there already a JIRA for that issue?
