Unable to run the Java Concurrent Program in R12.2.10.
These programs were previously working in R12.1.3.

In R12.1.3, had the below value in Java Control Panel (JCP) Option:
-classpath /applmgr/<instance name>/apps/apps_st/comn/java/classes:/applmgr/<instance name>/apps/apps_st/comn/java/lib/appsborg.zip:/applmgr/<instance name>/apps/apps_st/comn/java/classes/proquest/*

In R12.210, have changed it as below:
