Motivation:
When searching for the delimiter, the decoder part within HttpPostBodyUtil
was not checking the left space to check if it could be included or not,
while it should.
Modifications:
Add a check on toRead being greater or equal than delimiterLength before
going within the loop. If the check is wrong, the delimiter is obviously not found.
Add a Junit test to preserve regression.
Result:
No more IndexOutOfBoundsException
Fixes#11334
