We should use jdouble and jfloat, or otherwise there will
be implicit argument conversion from uint64_t to double
when array_get_field_double() will be called in
vm_jni_release_double_array_elements() with jdouble
argument.
This bug caused that
gnu/java/awt/peer/gtk/FreetypeGlyphVector.getMetricsNative(IJ)[D
was returning corrupted array.
