Drools .drl files giving runtime error on ZOS

问题

I have created a runnable jar containing drools engine functionality (.drl files are also inside jar) while running on windows the output is fine but on ZOS I get the below error with respect to .drl files.

    java.lang.RuntimeException: Error while creating KieBaseÝMessage Ýid=1, kieBase=
