javaw.exe pdb not found

Question

I am building a java application which call some function of a c++ dll using jni. When I tried to build my dll I get a pop up saying that debugging information for 'javaw.exe' cannot be found or does not match.Cannot find or open the pdb file. I have already set my environment variable. Is it normal and if not is there a way to avoid it ?

Answer 1

Yes, it is normal.

Visual Studio is just saying you that it can't find pdb files required for showing C++ source code while debugging - but not your source code, but the source code of javaw.exe itself (which you don't need, as, if there is problem, the probability of finding bug is in your code, and not in Oracle's is pretty big).
