some time I am facing following exception on closing client by killing client in metadataAdapter
Exception in thread "TIMER FOR PUMPS PARKING DESTROYER" java.lang.NullPointerException
at com.iontrading.lightstreamer.dataadapter.MixedMeta dataAdapter.notifySessionClose(MixedMetadataAdapte r.java:205)
and i think because of this exception I am not getting unsubscription call at dataAdapter
Please let me know the reason of this exception
