  • What is the JRE caching policy for JBoss EAP 6 with oracle JDK 1.7 ? Is it forever or does it time out? If it does time out what is that value ?
  • Will the JBoss container cause any issues if the JVM DNS caching was turned off via java.security.Security.setProperty("networkaddress.cache.ttl","0") ?
