    Session and Memory Leak on Wildfly 10

    I recently re-wrote 10MinuteMail, my secure temporary email service, updating it from Seam 2 and JBoss 4.2 to Deltaspike and Wildfly 10.  Unfortunately I noticed a memory leak in the JVM.  During beta testing, the JVM heap usage would slowly grow, over 1-2 weeks until it reached an OOM (out of memory condition).

The book contains extensive performance/load […]
