Vikas~
I suspect your best bet is:
```
Schema<?> s = ....
Object o = s.newInstance();
if (o instanceof MessageOrBuilder) {
return ((MessageOrBuilder)o).getDescriptorForType();
}
return nullptr;
```
If you are using the JavaLite runtime, you may not have descriptor
information available, so this can produce nullptr.
