 From the bug I had opened, it was indicated that you can run this to get the
same result:

[jhelfman at dormouse.experts-exchange /usr/local/share/java/classes]$ java -cp
ecj-3.7.2.jar org.eclipse.jdt.internal.compiler.batch.Main -version
Eclipse Compiler for Java(TM) 0.B83_R37x, 3.7.2, Copyright IBM Corp 2000,
2011. All rights reserved.

Here is a bit from the log of the bug:
--- Comment #2 from Satyam Kandula <satyam.kandula at in.ibm.com> 2012-03-20

The Manifest.Mf is not including the main class! I will see what could be
done here. Otherwise, you could try out
%java -cp ecj.jar  org.eclipse.jdt.internal.compiler.batch.Main -version

I'll see if I can tune the shell script to output the same.
