             Summary: org.apache.jasper.runtime.BodyContentImpl memory leaking when using JSTL Simple tag what having body is scriptless
                 Key: WFLY-5973
                 URL: https://issues.jboss.org/browse/WFLY-5973
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 9.0.2.Final
            Reporter: Loc Ha
            Assignee: Stuart Douglas
            Priority: Critical


-- Create any JSTL Simple tag (SimpleTagSupport) that having body is scriptless
-- Create a JSP using the Simple tag
-- Request the JSP multi time
-- Using visualvm 1.3.8 to monitor the allocations of org.apache.jasper.runtime.BodyContentImpl --> You will see a lot of instance of BodyContentImpl created

-- Click on Perform GC on VisualVM --> The remainging BodyContentImpl didn't go down to ZERO ---> Leaking memory

-- Did the same test using Glashfish 4 --> When click on Perform GC --> BodyContentImpl went down to Zero --> No leaking memory.
