Beanshell catch（ex）：Exception还是Throwable？

Question

What type of exception is caught by the beanshell catch(ex): Exception or Throwable?.

Example:

try {
    .... } catch (ex) {     }

Answer 1

That loosely typed catch will catch everything " Throwable ." That will include Errors , Exceptions and their myriad children. You can easily confirm this with:

try {
  new Throwable("Something Exceptional");
} catch (ex) {
  System.err.println(ex.getMessage());
}

Answer 2

Throwable is a superclass (essentially) of Exception--anything that Exception catches will also be caught by Throwable. In general usage they are the same, you rarely (if ever) see other throwable types.
