[jira] Issue Comment Edited: (FELIX-2466) Failure to resolve
gemini-web bundles
[ https://issues.apache.org/jira/browse/FELIX-2466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12886454#action_12886454 ]

----------------------------------------------------------------
Technically, it does look like there is a bug in the resolver, although it is not exactly what you might expect. The com.springsource.org.apache.jasper.springsource has this metadata:
Fragment-Host: com.springsource.org.apache.catalina.springsource;versi
on="[6.0.20.S2-r5956, 6.0.20.S2-r5956]"
In reality, this declaration is somewhat faulty since it should be using "bundle-version" as the matching attribute for the host, not "version". The Felix resolver obeys the attribute and doesn't find any matching host; however, this appears to not comply with the spec, since the spec only defines one known attribute (i.e., bundle-version) and doesn't specifically allow arbitrary attributes on the Fragment-Host header.
In short, we need to modify our manifest parser to strip unknown attributes from the Fragment-Host header, then it should start to work. Additionally, someone should tell the SpringSource people to use bundle-version instead of version. :-)

> The same set of bundles resolve ok in equinox.
> Guessing it might have something to do with fragments as they're definitely in use.
