Gaining Access to the JCK
The Java Compatibility Kit (a.k.a., the JCK or TCK for Java SE) is available at no charge to developers who are planning to deploy a compatible Java implementation based on code derived from OpenJDK, or are participating in OpenJDK research, bug fixes, code enhancement and/or ports to other hardware/software architectures.
The JCK is made available under the terms of the OpenJDK Community TCK License Agreement (OCTLA). The current version of the OCTLA is for Java SE 9 or later (OCTLA JDK 9 V 3.0). Please contact oracle-ca_us [at] oracle [dot] com with any questions.
Блин, это значит, меня обманули, или я неправильно понял. Но я точно слышал, что это платно.
