Subject [jira] Created: (FELIX-759) Version range in import declaration creates a filter using invalid operators (<,>)

Version range in import declaration creates a filter using invalid operators (<,>)

                 Key: FELIX-759
                 URL: https://issues.apache.org/jira/browse/FELIX-759
             Project: Felix
          Issue Type: Bug
          Components: Maven Bundle Plugin
    Affects Versions: maven-bundle-plugin-1.4.3
         Environment: Maven Bundle Plugin 1.4.3
Apache Felix Bundle Repository (1.2.0)
Apache Felix 1.2.1/Equinox 3.4.0

            Reporter: Dirk Mahler

If a version range is given for an import-declaration (e.g. bundle http://www.springsource.com/repository/app/bundle/version/detail?name=com.springsource.javax.jms&version=1.1.0)
the maven bundle plugin creates version filters for the OBR repository which might contain
the operators < and >, e.g.:

<require extend="false" filter="(&amp;(package=javax.transaction.xa)(version&gt;=1.0.1)(version&lt;2.0.0))"
multiple="false" name="package" optional="true">Import package javax.transaction.xa ;version=[1.0.1,2.0.0)</require>

These operators are currently not supported by Felix and Equinox, the OSGi specification (at
least 4.0.1) only states "<=" and ">=" as valid ones.
The resulting problem are exceptions while reading the repository descriptor:

Caused by: org.osgi.framework.InvalidSyntaxException: expected ~=|>=|<=
        at org.apache.felix.framework.FilterImpl.<init>(FilterImpl.java:81)
        at org.apache.felix.framework.BundleContextImpl.createFilter(BundleContextImpl.java:104)
        at org.apache.felix.bundlerepository.RequirementImpl.setFilter(RequirementImpl.java:57)

A simple patch for the class org.osgi.impl.bundle.obr.resource.BundleInfo.java is attached
to this issue. The solution is to replace (version<2.0.0) by (!(version>=2.0.0))
