How to retrieve full exception message from compiled jar without changing the code?

Java application terminates with exception:

I now that NumberFormatException should contain "For input string" text. What can I do to view the message text for that exception?

Not from code, this is a compiled jar application which is run with bat file like this:

java -cp "%CP%" %JAVA_OPTS% liquibase.integration.commandline.Main %CMD_LINE_ARGS%

There may not be a message for you to view. If the NumberFormatException had a detail message, it would be part of the stack trace. Here is the javadoc for NumberFormatException. You will note that there's no guarantee the exception will have a detailed message. In fact, it has a no-argument constructor which is documented to construct "a NumberFormatException with no detail message".

Additionally, here is the main constructor for the OpenJDK implementation of the BigDecimal class. If you look through it, you'll see that it throws NumberFormatExceptions with no detail message in a few places.
