-------------------------------------

Hi,

as workaround it should be possible the register a {{ServletContextListener}} 
in the {{web.xml}}:

{code}
<listener>
        
<listener-class>org.apache.olingo.odata2.jpa.processor.ref.web.JPACleanUpListener</listener-class>
</listener>
{code}

Which calls the {{ODataJPAContextImpl.unsetContextInThreadLocal();}} after the 
servlet context expires (get destroyed):

{code}
/**
 */
public class JPACleanUpListener implements ServletContextListener {
  @Override
  public void contextInitialized(ServletContextEvent servletContextEvent) { }

  @Override
  public void contextDestroyed(ServletContextEvent servletContextEvent) {
    ODataJPAContextImpl.unsetContextInThreadLocal();
  }
}
{code}

Best Regards,
Michael

>             Project: Olingo
>          Issue Type: Bug
>          Components: odata2-jpa
>    Affects Versions: V2 2.0.4
>         Environment: java 8, wildfly 8.2, Linux
>            Reporter: Manuel Blechschmidt
>
> The following code produces a memory leak in an application server:
> {code:title=org.apache.olingo.odata2.jpa.processor.core.ODataJPAContextImpl}
>   @Override
>   public void setODataContext(final ODataContext ctx) {
>     odataContext = ctx;
>     // This produces a memory leak on wildfly
>     setContextInThreadLocal(odataContext);
>   }
> {code}
> I removed the setContextInThreadLocal and it worked afterwards. I searched 
> the whole code how this variable is normaly removed but was not able to find 
> the clean way to solve this problem.
