When a new API module is redeployed, the GraphQL servlets is reinitialized in the next request. When all APIs from CE and DXP are loaded and an API module is redeployed the GraphQL servlet initialization fails in the next request processing the Instance entity inside portal-workflow-metrics API. Seems more like a coincidence than totally related with this API.

If the portal-vulcan-impl module is redeployed the issue is solved.

Steps to reproduce it:
1. Configure Liferay with DXP profile and run `ant all`
2. Start the portal
3. Make a GraphQL request. Everything is working fine.
4. Redeploy a module like headless-delivery-api
5. Make a GraphQL request. GraphQL servlet fail to init
