I might be wrong but I think they stopped working on major new versions for a decade. There seems to be Java 6 or 1.6 or whatever for a really long time. Like Netscape's version 4.
1.6 and 1.8 and the like were major releases. While LTS doesn’t have a well-defined meaning for OpenJDK, in general 11+6*n are the versions that are considered LTS (due to other vendors providing paid support for those).
Let’s not read more into arbitrary version numbers.
But that is not the java naming scheme. Java stared using normal major version numbers back in the Java 5 days. They've developed major releases continuously for decades.
