Issues found in plugins as a result of updating Jackson from 2.6.5 to 2.13.3
om Class Serialization Errors
- ML Plugin 1.0.0
- Datasets Plugin 1.0.0
Updating Jackson from 2.6.5 to 2.13.3 causes issues with om class serialization. If Swagger sees an om class as a @ResponseBody or a @RequestBody, it will try to document that class. Because of the recursive object structure in om classes, Swagger can't figure out how to document the class and will eventually time out which will cause the Spring context initialization to fail. This timeout failure may take a long time to resolve (10-20 minutes or more), and you will find exceptions like the following in spring.log and/or application.log.
Example spring.log output
2022-06-08 08:35:23,737 [main] ERROR org.springframework.web.context.ContextLoader - Context initialization failed org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is com.google.common.util.concurrent.ExecutionError: java.lang.OutOfMemoryError: Java heap space

Unit Test Failures
