Open Source version references dual license

[lukaseder]

The jOOQ Open Source Edition's files and their file headers should all be ASL 2.0 licensed. However, some individual files reference the dual license:

jOOQ/jOOQ/src/main/java/org/jooq/impl/CreateIndexImpl.java

Lines 1 to 37 in b04f805

This happened by mistake

[lukaseder]

The tool that produces the jOOQ Open Source Edition from the commercial distribution cannot handle a file header starting with Javadoc format (/**\n), only with multiline comment format (/*\n)

Fixed in jOOQ 3.13.0. Backport scheduled for 3.12.4 (#9532)
