Generator "spin loops" (?)

[vorburger]

This proto, when used similarly to this, as shown below, seems to cause this protoc plugin to go into a "spin loop" (seemingly infinite high CPU usage):

PLUGIN=$(go env GOPATH)/bin/protoc-gen-jsonschema

mkdir -pv docs/models/enola/schemas/
protoc \
  --plugin="${PLUGIN}" \
  --jsonschema_opt=allow_null_values \
  --jsonschema_opt=file_extension=schema.json \
  --jsonschema_opt=disallow_additional_properties \
  --jsonschema_out=docs/models/enola/schemas/ \
  core/lib/src/main/java/dev/enola/core/enola_core.proto

Just thought I would let you know.
