Issue/Introduction

There are many error messages about "BAD UNSERIALIZE" for different SOI alarms written to \CA\SOI\tomcat\logs\catalyst.log on the SOI manager.
Here is one example of such error message:
 
2018-11-06 11:31:50,476 ERROR [JMS XXXXX.XXX.XXX.XXX] () impl.SessionImpl.logSDODiagnotic(1494) SOI - ****** BAD UNSERIALIZE ******

XMLHelper instance class loader: java.net.URLClassLoader@68b1d858
XMLHelper instance class location: file:/D:/CA/SOI/tomcat/lib/tuscany-sdo-impl-1.1.1.jar
