Building lwjgl

[Zol]

Hi I have been trying to build lwjgl 2.x in eclipse with ant scripts. But i get error when running ant compile_native:

Buildfile: C:\Users\xx\git\lwjgl\build.xml
-initialize:
compile:
headers:
    [javah] Exception in thread "main" java.lang.NullPointerException
    [javah]    at com.sun.tools.javah.JavahTask.run(JavahTask.java:509)
    [javah]    at com.sun.tools.javah.JavahTask.run(JavahTask.java:335)
    [javah]    at com.sun.tools.javah.Main.main(Main.java:46)
BUILD FAILED

So if somebody can give some tips with issue i would be very gratefull.
I have run ant generate-all and ant compile before running ant compile_native.

My setup is windows 7 with jdk7(64bit) + visual studio 2010. Any tips for troubleshooting?
