Add profile to build on JDK 14 (#10148)

Motivation:

JDK 14 was released and need some special settings to be able to build with. Also there seems to be one regression that we need to workaround for now.

Modifications:

- Add maven profile for JDK 14
- Update blockhound version to be able to work on JDK 14
- Add workaround for possible JDK 14 regression

Result:

Be able to build on JDK 14
