Summary:              Export slf4j packages in version 1 and 2 in OSGi-Manifests
Issue Type:           Bug
Assignee:             SLF4J developers list
Created:              14/Mar/23 11:17 AM
Priority:             Major
Reporter:             Ceki Gülcü
Description:
  Components:           Core API
  Created:              14/Dec/22 11:11 PM
  Environment:
    The documentation claims that SLF4J-2 is binary compatible to slf4j-1, from a
  client perspective:
     * [https://www.slf4j.org/faq.html#compatibility]
     * [https://www.slf4j.org/faq.html#changesInVersion200]
  
    In order to ease migration to slf4j-2 in the OSGi world and to allow the usage
  of libraries that are build against slf4j-1 and therefore have a Import-Package
  version range with exclusive upper-bound of 2 in an OSGi runtime that has
  SLF4J-2 installed it would be beneficial if slf4j-api would export its packages
  in version 1 (probably the latest one) and two.
    Eventually the Manifest of slf4j-api would have an entry like the following
  (plus uses-constraints):
    {code:java}
    Export-Package:
     org.slf4j;version="1.7.36",
     org.slf4j;version="2.0.7",
     org.slf4j.event;version="1.7.36",
     org.slf4j.event;version="2.0.7",
     org.slf4j.helpers;version="1.7.36",
     org.slf4j.helpers;version="2.0.7"
     org.slf4j.spi;version="1.7.36",
     org.slf4j.spi;version="2.0.7"
    {code}
