Description

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="(&(package=javax.transaction.xa)(version>=1.0.1)(version<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))
