Is memory out of bound exception or error?

Question

Is memory out of bound exception or error? We usually get this during project deployment on the server. It might be a basic question. I googled it but I could not find relevant answer so posting here.

Error I got:

Invocation of init method failed; nested exception is java.lang.OutOfMemoryError: allocLargeObjectOrArray - Object size: 8216, Num elements: 2049

And how can we handle this?

Could you post the full error message? Its quite hard to guess what you mean from the little info you provide. — Dawnkeeper, Feb 02 '16 at 12:20
check this and you will see what it extends https://docs.oracle.com/javase/7/docs/api/java/lang/OutOfMemoryError.html — Petter Friberg, Feb 02 '16 at 12:23
Please be a lot more specific than you have so far, OP. Everyone seems to be trying to guess what you mean. — Andrew Regan, Feb 02 '16 at 12:28
@AndrewRegan, was trying to find a duplicate before answering. — Petter Friberg, Feb 02 '16 at 12:36
You're probably right, Petter, but question definitely needs an edit. — Andrew Regan, Feb 02 '16 at 12:37
IndexOfOutBoundException is a RuntimeException and OutOfMemoryError is an Error. You need to know what the actual name of the error is. — Peter Lawrey, Feb 02 '16 at 12:53
Thanks All. Here it is the error: Invocation of init method failed; nested exception is java.lang.OutOfMemoryError: allocLargeObjectOrArray - Object size: 8216, Num elements: 2049 — manohar e, Feb 03 '16 at 07:24

java.lang.OutOfMemoryError extends java.lang.Error and not java.lang.Exception

catching Exception you will miss it

try{
....
}catch(Exception ex){
 //will not catch OutOfMemoryError, since it does not extend Exception
}

catching Throwable, you will hit'em both..

try{
....
}catch(Throwable ex){
 //will catch both Exception and OutOfMemoryError, they both extend this
}

Whether it is good or not to catch Throwable is another question see this Is it a bad practice to catch Throwable? (Thanks to @Dawnkeeper for link)

just adding that catching Throwables might not really help you as Errors tend to not be recoverable. see [Here](http://stackoverflow.com/questions/6083248/is-it-a-bad-practice-to-catch-throwable) – Dawnkeeper Feb 02 '16 at 12:31
