JAVA SE 8, the most popular Oracle-licensed release, was in principle a free software. Since April 16, 2019, subsequent Java releases and updates require license fees. Therefore, in order to avoid additional fees related to commercial use of Java by our customers, we decided to migrate the system to OpenJdk.

You can still use older versions of Java (<= 1.8M update 8u202), but their inability to update may pose problems in the future, as these versions will not protect against potential unpatched security holes. The threats detected lately, utilizing TLS 1.0 and TLS 1.1 protocols clearly prove the importance of software updates. Switching to the free OpenJDK version will ensure stable security patches and the development of the platform and tools in the future.
