Description
A new option is available to provide more helpful `NullPointerException` messages:
-XX:+ShowCodeDetailsInExceptionMessages
If the option is set, on encountering a null pointer, the JVM analyzes the program to determine which reference was `null` and then provides the details as part of `NullPointerException.getMessage()`. In addition to the exception message, the method, filename, and line number are also returned.
By default, this option is disabled.
