It is probably better to ask this on a jdk oriented mailing list, and
not on a list which at list nominally is devoted to mechanical sympathy.

Hello,
I'm trying to understand what happens inside the SocketDispatcher
native method "write0". I want to make some experiments with it
therefore I would like to learn how to recompile and debug native
methods from the JDK on Linux. That's a knowledge I find important to
have (i.e. change JDK native code).
Here is the SO post:
http://stackoverflow.com/questions/43360875/how-to-change-java-native-code-c-implementation-from-the-jdk-socketchannelimp
Any genius would know how to do that?
Basically I would like to know:
1. Where is the C/C++ code for write0 for Linux?
2. How do I recompile (gcc command-line?) the C/C++ code for write0 on
Linux?
3. How do I start my JVM and make it use my new compiled native code
for write0 on Linux?
Thanks!
