cannot execute binary file: Exec format error

Semi-colon in bash is used to separate commands. So in your case

java -cp .;aa/bb/cc/dd/Main.jar aa.bb.cc.dd.Main

java -cp . and aa/bb/cc/dd/Main.jar aa.bb.cc.dd.Main are considered as two separate commands and executed in sequence.

The issue can be fixed by changing the ";" to ":".

The path delimiter for java class path is ":" and not ";".
