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

["Richard S. Hall (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12838255#action_12838255 ] 

Richard S. Hall commented on FELIX-759:
---------------------------------------

Just as a follow up, since I saw this issue due to some JIRA changes...this was discussed in CPEG at one point in time and the idea of adding such operators to Filter was rejected...at least for now.

> 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))
