[jira] [Created] (GERONIMO-5872) geronimo-servlet_3.0_spec-1.0.jar
incorrectly applies semantic versioning to servlet packages
geronimo-servlet_3.0_spec-1.0.jar incorrectly applies semantic versioning to servlet packages
---------------------------------------------------------------------------------------------
Key: GERONIMO-5872
URL: https://issues.apache.org/jira/browse/GERONIMO-5872
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: specs
Affects Versions: 3.0-M1
Reporter: Alasdair Nottingham
The gernomio-servlet_3.0_spec-1.0.jar incorrectly exports the javax.servlet packages as 2.6 and 3.0. The problem with this is if the Servlet spec were to make a semantically breaking API change the correct next semantic step for the javax.servlet packages would be 3.0. This means there is no way for an importer importing at [3.0,4.0) to know whether they will match the version that is the same as 2.6, or the version that is breaking from 3.0 resulting in deployment and runtime problems.

Alasdair Nottingham commented on GERONIMO-5872:
-----------------------------------------------
The OSGi Enterprise Expert group specified in the Enterprise 4.2 spec that Servlet 2.5 packages be versioned at 2.5, so we should expect semantic versions from that point on.
The correct semantic version from a 2.5 baseline is 2.6. Users who expect the packages to be at version 3 are expecting something which does not follow the best practices for semantic versioning.

David Jencks commented on GERONIMO-5872:
----------------------------------------
Semantically, shouldn't servlet spec package versioning be at something like 1.8?
What version do you think we should export?
What do we do about the users of the servlet api that expect the 3.0 api classes to be exported at 3.0?
Is there any agreement among anyone what the osgi package version should be for javaee spec apis? Is it documented anywhere?
