– 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.
