Hi Ivan,
this looks like a good idea.
Maybe the pattern to do new (std::nothrow), then check for 0 and throw OOM is a
good candidate for a Macro which would keep the code a bit more compact?
Yes, I agree that this code needs some refactoring.
Let's use the overloaded 'operator new':

Subject: [jdk9] (S) RFR: 8165463: Native implementation of sunmscapi should
use operator new (nothrow) for allocations
Hello!
In the native layer of sunmscapi provider, for memory allocations the
::operator new() is used.
In (a very unlikely) case of failure, it will raise a C++ exception of
type bad_alloc, which is bad, as we don't have handling code.
One simple way to improve the situation would be to use ::operator new
(std::nothrow), which will just return zero to indicate a failure
instead of throwing an exception.
Then we can (try to) throw a Java exception of type OutOfMemoryError.
Would you please help review the fix?
