Review Comment:
   Thank you - indeed a more focused fix, bringing a partitial solution with 
minimal/no negative side effects.  At this point however I think it would be 
helpful to also have logging as in `Scripting.java`. Adding the catch clause 
for `ServiceConfigurationError` fixes the problem reported in #7245 (not being 
able to generate a HTML/JS application), but there is also no info shown, as 
the exception is swallowed. This also does not need an additional guard as the 
code that could cause the exceptions is entered at most once (`disable` is used 
as guard).
