Richard Zowalla commented on TOMEE-4194:
----------------------------------------

Snakeyaml 2.0 has breaking changes (in constructors) and cannot simply be 
updated within TomEE. It needs to be addressed by the maintainers of OpenAPI 
impl.

When you use SnakeYAML to configure your application you are totally safe 
(given that you control the input). The only issue is when the data to parse 
comes from untrusted source - meaning it is downloaded from unknown source 
without authentication and authorisation, cf. 
https://bitbucket.org/snakeyaml/snakeyaml/src/master/

For now, we need to wait until it is addressed by the 3rd party libs.
