Oracle JDK or OpenJDK - Your Choice!

MockMotor supports both Oracle JDK and OpenJDK.

Oracle JDK

Oracle has recently changed the usage conditions for its JDK. It now requires a license.

The price is not high, especially for companies. However, the move was met with understandable resistance.


At the same time, OpenJDK remains free and is installed on Linux boxes as a default.

Which one does MockMotor Support?

MockMotor supports both.

Functional Testing

Each MockMotor’s build is tested against a few JDKs:

  • Oracle 1.8
  • Oracle 13.0
  • OpenJDK 1.8
  • OpenJDK 11.0

Only if all tests pass for all JDKs, the build is considered successful.

Performance Testing

In addition to functional tests, several performance tests are run against each of JDKs to spot possible performance issues.
