Hi,
This is getting a bit hostile for no reason Thinking about
alignment gives an interesting solution.
1) Strings are not null-terminated
2) For most strings the alignment gives the VM room to terminate in
place when GetStringChars is called
3) Copy strings that can't be terminated in place

This is just ridiculous. An average Java app has tons of Strin

Hi,
Apologies if you receive this twice. I sent it via nabble and it's

I'm trying to understand a piece of code in java.io . Let me try to
explain:
When you look into WinNTFileSystem.c in the method
getBooleanAttributes(), you see that the file object is converted to a
WCHAR* using fileToNTPath(). In io_util.c, fileToNTPath(), the filename
