It looks to me like there are two issues here:
* I do not think we should have put a {{module-info.class}} into a jar file
meant for Java 7.
* This might not be BCEL's fault: It just parses the class file you give it,
or a zip file you give it, or an input stream; there is no way to tell without
knowing the version of Tomcat and BCEL.
As a workaround, you can remove this class file from the jar file.

Hi [~ggregory]
Really appreciate your input on this, it makes sense and the work around does
work fine.
However modifying the jar manually will not be an apt solution for us as we
have multiple applications and environments and it might be not possible to
maintain a custom version for log4j-api alone. It will be prone to errors.
Kindly check on this, Thank you.
FYI Tomcat VERSION:-8.0.23
