Used olap4j 1.2.0 and olap4j-xmla 1.2.0 With JBoss 5.1 no errors, when app running on WildFly see next errors in logs:
org.olap4j.OlapException: Internal error: hierarchy '[dimP].[ID P]' not found in cube 'LCube'
and
java.lang.RuntimeException: recursive population
Same olap4j libs, same connection setting, same cube. Furthermore, month ago all works perfectly with WildFly with same libs and code.
Flushing all connections fixed problem.
