We need an option to disable that (and other) features/interceptors... Now we have hardcoded in Component.initDefaultInterceptors(): if ( getScope()==CONVERSATION ) { addInterceptor( new Interceptor( new ManagedEntityIdentityInterceptor(), this ) ); } and in ManagedEntityIdentityInterceptor.aroundInvoke(..) we have: ... finally { if ( !PassivatedEntity.isTransactionMarkedRollback() ) { entityRefsToIds(ctx); } } That code (PassivatedEntity.isTransactionMarkedRollback()) was trying to lookup jndi, and returning false if it's fail...
