Michael Osipov closed HTTPCLIENT-1919.
--------------------------------------
    Fix Version/s:     (was: Stuck)
       Resolution: Won't Fix

No one has provided a PR, we don't have any experience with OSGi. We have to be 
honest and say that we cannot fix this.

> 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.
