Justin Edelson updated HTTPCLIENT-1749:
---------------------------------------
Description:
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.
