#15 JVM crash on OPC error item

[zack]

Invoke any operation on item form Matrikon.OPC.Simulation server group "Simulation Items.Read Error" than get JVM crash.

Attached modified SynchReadGroupExample.java with added
OpcItem item4 = new OpcItem("Read Error.Int1", true, "");

It looks taht correcting UOPC.pas function function TOPC.synchReadItem((PEnv: PJNIEnv; group, item: JObject): JObject;
should help.
Simply when quality is bad don't set value from the null pointer.
