      Description

        dcstartup script uses -agentlib:am_ibm_16 as one of the command line parameters to run the application.
        Error log: dcstartup Issue: Could not find agent library am_ibm_16 on the library path, with error: libam_ibm_16.so
        The agentlib calls native jvm agent code, which does a dll_load to load the library files. OpenJDK hotspot can only load libraries with .so extension and throws an error when libraries have .a extension.

        Solution :
        Providing an alternate path for loading shared objects with .a extension.
        If the loading of a shared object ,for e.g obj.so, fails, we check if there is an archive file with the same filename i.e obj.a and perform the loading again.
