What version of the product are you using? On what operating system?
JNativeHook-1.1.0_rc3 on Mac OS X 10.7.4 with JVM version 1.7.0_04

Please provide any additional information below.

Works just fine on 6.

I tried building it from SVN on my Mac, but that did not end well.

Looks like it did not find the correct include file.  Can you attach the 
generated build.properties file?

First off, do i really need to build it myself to have it work with JDK7?

I manually set JAVA_HOME to point to my JDK7 VM.

You should not need to build it your self.  It looks like Apple has botched 
something with their new JDK bundle.  I don't own a Mac that is new enough to 
run 10.7 so I am looking into other ways of testing this.

Alright, compiling requires one more include path at the end of native.cc.args: 
-I/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/include/darwin  

It still doesn't run after it compiles.  That problem seems to be caused by the 
Class objects getResourceAsStream method returning null on OS X.  See:  
http://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#getResourceAsStrea
m(java.lang.String) 

That method appears to function correctly on Windows, Linux and Solaris using 
the binaries provided by Oracle.  I am about 5 minutes away from calling this a 
JRE bug on OS X probably due to a botched custom class loader for the platform. 
 I will dig around a bit more and see if I can find a solution but I believe 
that a bug report to oracle will be required.  You should be able to work 
around the problem by specifying the java.library.path manually (Ex: java 
-Djava.library.path=/path/to/dylib/ -jar JNativeHook.jar)

Scratch the bug, I found the issue.  It is looking for the wrong filename.  For 
some reason Java 7 returns .dylib for System.mapLibraryName() instead of jnilib.

Thanks for the super quick fix.

Now, unless there will be a new RC soon, I will need to build it from source 
anyway.

What does the process look like to generate a jar with Mac, Linux and Windows 
natives?

p.s. this is what we're building: https://github.com/davidleibovic/keymusix

Np. Generating cross compiled binaries is a pain.  There is a binary attached 
to bug #19 that covers up the the current trunk.  There maybe some problems 
with that binary but I will update it as that bug progresses.  I am trying to 
resolve bug #18 before the final 1.1 but if that takes to much longer it may 
need to wait.  If you need a custom build just let me know.  It only takes a 
few seconds to run it though the cross compiler.
