[weld-dev] Unique BeanIdentifierIndex every time I restart a server

Hello. I've been investigating a bug relating to session failover and I've noticed that my BeanIdentifierIndex has a different hash every time I start and stop the server. This is consistent across every app I tried. For example: Upon starting the server I see my debug output GREP BeanIdentifierIndex [hash=591986009, indexed=3] 0: WELD%AbstractBuiltInBean%invalidBeansXml#com.ibm.ws.transaction.cdi_1.0.15.20161018-1920.additionalClasses%HttpSession 1: WELD%AbstractBuiltInBean%invalidBeansXml#invalidBeansXml.war%HttpSession 2: WELD%AbstractBuiltInBean%invalidBeansXml#org.eclipse.osgi.internal.loader.EquinoxClassLoader@d6318459[com.ibm.ws.org.jboss.weld.2.4.0:1.0.15.20161018-1920(id=108)].additionalClasses%HttpSession I stop the server, and start it again GREP BeanIdentifierIndex [hash=-375657379, indexed=3] 0: WELD%AbstractBuiltInBean%invalidBeansXml#com.ibm.ws.transaction.cdi_1.0.15.20161018-1920.additionalClasses%HttpSession 1: WELD%AbstractBuiltInBean%invalidBeansXml#invalidBeansXml.war%HttpSession 2: WELD%AbstractBuiltInBean%invalidBeansXml#org.eclipse.osgi.internal.loader.EquinoxClassLoader@b3a3f568[com.ibm.ws.org.jboss.weld.2.4.0:1.0.15.20161018-1920(id=108)].additionalClasses%HttpSession Same three classes but the hash is completely different. My question is simple. Is this the expected behaviour or is this a sign that something's gone wrong?
