> Memory Leak in OSGi support

> Key: HTTPCLIENT-1749
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1749
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.4.1, 4.5.2

> 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.
