Remove punctuation in Exception messages

See original GitHub issue

Many Exception messages contain exclamation marks (!) at the end of the Exception message, for example:

“Object must not be null!”

While this alerts the user to an immediate problem in his/her code, it could be construed as abrasive.

Additionally, using any form of punctuation in Exception messages is not conducive for chaining. Generally, in Java Exception/Error (Throwable) chaining, the messages from the underlying Exceptions (causes) are chained together with the outer, wrapping Exception, for example:

java.lang.IllegalArgumentException: "Message from the wrapping IllegalArgumentException followed by; Message of the caused by Exception"
  at ...
caused by: java.lang.IllegalStateException: Message of the caused by Exception
  at ...

That is, the Exception messages from the chain are appended and separated by the ;.

If the messages from the wrapping Exceptions in the Exception chain contain punctuation, then it can lead to confusing text:

java.lang.IllegalArgumentException: "Object must not be null!; Message of the caused by Exception"
  at...
caused by: java.lang.IllegalStateException: Message of the caused by Exception
  at ...

@martinsefcik - Thank you for bringing this to our attention. It would appear that this is the affected area of code and it could do with some more refactoring.

What we would be shooting for in this message is:

No property 'creat' found for type 'User'; Did you mean 'created'

I will look into this.
