> There is a memory leak in the HTTP Client OSGi support whereby the HttpProxyConfigurationActivator holds on to references to created HttpClient instances for the entire life of the httpclient-osgi bundle, which may be (and probably is in many cases) longer than the lifespan of individual HttpClient instances.
> The clients are added here: http://grepcode.com/file/repo1.maven.org/maven2/org.apache.httpcomponents/httpclient-osgi/4.4.1/org/apache/http/osgi/impl/OSGiHttpClientBuilder.java#58
> and not removed until http://grepcode.com/file/repo1.maven.org/maven2/org.apache.httpcomponents/httpclient-osgi/4.4.1/org/apache/http/osgi/impl/HttpProxyConfigurationActivator.java#115
> This can be relatively easily fixed by using weak references. In addition, access to this collection needs to be synchronized because the additions may come from multiple threads.
