Dear OpenJDK developers,
The versioning scheme of OpenJDK is described in JEP 223 [1] and JEP 322 [2].
The OPT string is described as: “$OPT, matching ([-a-zA-Z0-9\.]+) ---
Additional build information, if desired. In the case of an internal
build this will often contain the date and time of the build.[1]”
Debian and Ubuntu use the OPT string to convey packaging information,
including the distribution (Debian or Ubuntu) and the package version.
The OpenJDK version string in stable releases of Debian has the
following package version format:
<upstream-version>-<version>~deb<debian
release-number>u<update-version>, e.g., “21.0.10+7-1~deb13u1”. Ubuntu
uses the same convention, e.g., “21.0.10+7-1~25.10”.
The OPT string sanitisation converts the OPT value to “1deb13u1” and
“125.10”, stripping the ‘~’ symbol.
I was wondering if it would be possible to file an enhancement issue
or JEP (if needed) to allow the ‘~’ symbol in the OPT version string.
I don't think this is an unreasonable proposal. Technically it should be
quite simple to implement in the build. I'm not sure what the process
for changing the definitions in the JEPs is though.
