JavaWriter uses regex syntax unsupported in Java <1.8

[dbichko]

JavaWriter.java in 3.6.3, line 121:

Matcher m = Pattern.compile("(?s:^.*?\\Rpackage\\s+(.*?);?\\R.*?$)").matcher(string);

\R is new in 1.8, which I don't believe is explicitly required for jOOQ.

Thank you very much for reporting this! This is a regression introduced with #4229 (#4230).

The linebreak matcher \R corresponds to "Any Unicode linebreak sequence, which is equivalent to \u000D\u000A|[\u000A\u000B\u000C\u000D\u0085\u2028\u2029]"

It was indeed introduced in Java 8 only, and must thus not be used in jOOQ for backwards compatibility.

This will be merged to 3.6.4 as #4583

Fixed for jOOQ 3.7. We'll hopefully be able to publish a fix by Tuesday this week in 3.6.4.

This is now fixed and published also in 3.6.4

[dbichko]

Thanks for the really quick fix!

[lukaseder]

You're welcome. This was a real show-stopper...
