Commit e3d04ee01 (issue #5240) introduced unsafe add/put methods for optional
list/map parameters. This change maintains the spirit of issue #5240 (optional
containers are null by default) while still making add/put calls safe. It does
this by checking for null first and, if so, initializing it with an empty
container.
Also updated the affected samples using the various scripts in bin/.
* set list to null in java if not required
* update petstore sample for java server stub
* update sample for msf4j
* add null assignment to new list/map in java
* Issue #4606 (Spring) SubClass annotations are missing from the base class
* Issue #4606 (Spring) SubClass annotations are missing from the base class
* Commit updated samples from ./bin/spring-all-pestore.sh
This covers the usages that weren't fixed in #3825
Triple mustache is required because annotations may contain chars like
"=" that would be mistakenly encoded.
