[Bug 61781] New: NPE in PersistentProviderRegistrations.writeProviders() if layer or app context are null

https://bz.apache.org/bugzilla/show_bug.cgi?id=61781

            Bug ID: 61781
           Summary: NPE in
                    PersistentProviderRegistrations.writeProviders() if
                    layer or app context are null
           Product: Tomcat 8
           Version: 8.5.23
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: lazar.kirchev@gmail.com
  Target Milestone: ----

PersistentProviderRegistrations.writeProviders() throws NPE if it tries to
persist a provider with null layer or app context. The NPE is caused by passing
null to Writer.write(). However, it is acceptable for a Provider to have its
layer and/or app context null.

It is allowed by the spec and there is logic which supports this in the
AuthConfigFactoryImpl. So the layer and the app context should be treated as
optional, just as the description is treated.
