[jira] [Commented] (HTTPCLIENT-1919) Equinox SAXException when
starting OSGi module httpclient-osgi-4.5.5.jar
[ https://issues.apache.org/jira/browse/HTTPCLIENT-1919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16859588#comment-16859588 ]
Michael Osipov commented on HTTPCLIENT-1919:
--------------------------------------------
[~olegk], I'd say this is a won't fix because OSGi support has been dropped in 5.0 and I don't think that someone of us can fix this.

> Key: HTTPCLIENT-1919
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1919
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 4.5.5
> Environment: Liferay 7.1 alpha
> Reporter: Jesse Rao
> Priority: Minor
> Labels: osgi
>
> This error occurs when starting Liferay 7.1 alpha when the OSGi module httpclient-osgi-4.5.5.jar is used:
> {{2018-04-26 14:40:20.891 ERROR [main][org_eclipse_equinox_metatype:97] Unable to parse metadata XML at "bundleentry://45.fwk1343457451/OSGI-INF/metatype/metatype.properties" for bundle ID "45" with symbolic name "org.apache.httpcomponents.httpclient". }}
> {{org.xml.sax.SAXException: Fatal Error: URI=null Line=1: Content is not allowed in prolog.}}
> {{ at org.eclipse.equinox.metatype.impl.DataParser$MyErrorHandler.fatalError(DataParser.java:856)}}
> The issue is that the metatype.properties file is being parsed as XML (but is not XML). I believe the problem is that the metatype.properties file in httpclient-osgi-4.5.5.jar is in the wrong location.
> According to the OSGi spec, only metatype XML files should be in the OSGI-INF/metatype folder. See [https://osgi.org/specification/osgi.cmpn/7.0.0/service.metatype.html#d0e16879|https://osgi.org/specification/osgi.cmpn/7.0.0/service.metatype.html#d0e16879]
> However, in httpclient-osgi-4.5.5.jar, there are two files in this folder: metatype.xml and metatype.properties.
> The spec indicates that metatype localization files should go in the OSGI-INF/l10n folder. See [https://osgi.org/specification/osgi.core/7.0.0/framework.module.html#i3189742]
> Moving the metatype.properties from OSGI-INF/metatype to OSGI-INF/l10n should solve the problem.
