null output when trying to load the following sample swagger specs

[guptasu]

Test files live inside directory:

https://github.com/googleapis/api-compiler/tree/master/src/test/java/com/google/api/tools/framework/importers/swagger/testdata

library_example_yaml.yaml
additional_properties.json
top_level_security_ext.json
x_google_allow_extension_all.json
x_google_allow_extension_all_with_existing_catchall_methods.json

@timburks May be the change you are making currently to make some real world swagger files work, would automatically fix this problem.

These specs all load following this commit. The problem was that the generator was missing support for pattern properties at the top level.
