The milestone 1.9.0 does not contain the fix for the regex at line

[onlinemax]

When downloading the milestone 1.9.0 tar.gz file (which is the latest) at the url: (https://download.eclipse.org/jdtls/milestones/1.9.0/).
The bin/jtdls.py does not contained the updated regex:
matches = re.finditer(r"(?<=version\s\")(?P<major>\d+)(\.\d+\.\d+(_\d+)?)?", out)
and still has the old one:
matches = re.finditer(r"(?P<major>\d+)\.\d+\.\d+", out)

Making the same error described in the issue of: https://github.com/eclipse-jdtls/eclipse.jdt.ls/issues/2060

I just had a look at https://github.com/eclipse-jdtls/eclipse.jdt.ls/blob/master/CHANGELOG.md#1110-may-5th-2022 , which would list eactly which issues/changes were made for which milestone. Looks like it was fixed in 1.11.0. 1.9.0 was released on March 3rd 2022, but the issue wasn't reported until mid-April 2022.

Closing for now as I think the timelines are pretty accurate as to what happened. Usually, it's best to keep on a newer version of JDT-LS as there are many improvements from each release.
