src/solaris/native/sun/awt/awt_InputMethod.c file is full of "ifdef XAWT" preprocessor instructions. As we don't support MAWT anymore since jdk7 so can we safely get rid of them. I hope we don't have dependencies on Motif somewhere.
It would be a pure cleanup but it also would simplify the code clarity.
In particular following usages may be revised:
1) #ifdef XAWT_HACK

2) JNIEXPORT jboolean JNICALL
#ifdef XAWT
Java_sun_awt_X11_XInputMethod_openXIMNative(JNIEnv *env,
                                          jobject this,
                                          jlong display)
#else
Java_sun_awt_motif_MInputMethod_openXIMNative(JNIEnv *env,
                                          jobject this)
#endif
