== Why is this an issue?
|
|
|
|
``++Throwable++`` is the superclass of all errors and exceptions in Java. ``++Error++`` is the superclass of all errors, which are not meant to be caught by applications.
|
|
|
|
|
|
Catching either ``++Throwable++`` or ``++Error++`` will also catch ``++OutOfMemoryError++`` and ``++InternalError++``, from which an application should not attempt to recover.
