OpenJDK is becoming a popular alternative to the commercial version of OracleJDK. Oracle will not charge companies if they are on the current version of OracleJDK but their release cadence (sometimes as quick as 6 months) makes it difficult for companies to keep pace. Oracle argues that the releases are not "major" releases so the migration is not as daunting a task as many perceive it to be [1]. Java applications running in the ITC data center are on OracleJDK 8.
