       Using 1.5.0_09 symbol files allows to translate address awt.dll+0xe9299
       back:

      0:000> ln awt+0xe9299
      ../../../src/windows/native/sun/windows/awt_Window.cpp(1185)
      (6d0e9270) awt!AwtWindow::IsFocusableWindow+0x29 | (6d0e9320)

       Looking into source code gives:

      1181 JNIEnv *env = (JNIEnv *)JNU_GetEnv(jvm, JNI_VERSION_1_2);
      1182 if (env->EnsureLocalCapacity(2) < 0) {
      1183 return FALSE;

      1189 FocusableWindowStateID = env->GetFieldID(windowClass, "focusableWindowState", "Z");
      1190 env->DeleteLocalRef(windowClass);
      1191 }
      1192
