In what situations should one catch java.lang.Error
on an application?
Generally, never.
However, sometimes you need to catch specific errors.
If you're writing framework-ish code (loading 3rd party classes), it might be wise to catch LinkageError
(no class def found, unsatisfied link, incompatible class change).
I've also seen some stupid 3rd-party code throwing subclasses of Error
, so you'll have to handle those as well.
By the way, I'm not sure it isn't possible to recover from OutOfMemoryError
.
