JNI: fix error float argument to 'va_arg' is promotable

Browse Source 
If the native method contains a jfloat parameter, I get
the warning/error:
 Second argument to 'va_arg' is of promotable type 'JNITypeForArg<float>'
(aka 'float'); this va_arg has undefined behavior because arguments will
be promoted to 'double'
