The compilation of a program with isCOBOL is done in two steps. In the first step the isCOBOL Compiler (iscc) parses the COBOL source code and produces an intermediate Java source. In the second step the Java Compiler (javac) compiles the Java source into a class file.
In order to know the version of the isCOBOL Compiler used to produce the class file, run the following command:
iscrun -info PROGRAM.class
The command output will contain this text:
COBOL: java OBJECTs
It means that the program was compiled with a newer version of isCOBOL and your old version is not able to process the class, or
COBOL: compiled with isCOBOL build #??? ....
The ??? number tells you the build number. Here's a table of the build numbers and the isCOBOL version that matches it.

In order to check the Java version number in a .class file you can use the javap utility that is distributed with the JDK.
For example, the following command will report the version of a program named MYPROG.
javap -verbose MYPROG | grep majoror run
javap -verbose MYPROGand the version numbers will be reported in the first 5 lines.
