javah doesn't DTRT

[Solomon Douglas]

I'm finding that Blackdown javah version 1.2 is generating C
prototypes that are missing the package name.

In particular, I have the following in "FitNative.java":

   package fit;
   public class FitNative
   {
     static native String realName(String username)
       throws NoSuchUserException;
     static native String homeDirectory(String username)
       throws NoSuchUserException;
     static native boolean checkPassword(String username, String password);
     static { System.loadLibrary("FitNative"); }
   }

I compile the file: "javac FitNative.java".
Then I create the .h file: "javah -jni FitNative".

Then, when I look in "FitNative.h", I see the following prototypes:

   JNIEXPORT jboolean JNICALL Java_fit_FitNative_checkPassword
     (JNIEnv *, jclass, jstring, jstring);
   JNIEXPORT jstring JNICALL Java_fit_FitNative_homeDirectory
     (JNIEnv *, jclass, jstring);
   JNIEXPORT jstring JNICALL Java_fit_FitNative_realName
     (JNIEnv *, jclass, jstring);

If I use those names for my C functions, then at runtime I get a
java.lang.UnsatisfiedLinkError when I try to call one of the native
methods.  Instead, I have to edit the "FitNative.h" file so that the
functions include the package name: Java_fit_FitNative_checkPassword,
Java_fit_FitNative_homeDirectory, and Java_fit_FitNative_realName.

Is javah behaving incorrectly or am I invoking it wrong?
