RuntimeUtils.getAsReferenceWrapper(...) can cause precision loss

[Marcono1234]

The method RuntimeUtils.getAsReferenceWrapper(...) can cause precision loss:

• Java-Objective-C-Bridge/src/main/java/ca/weblite/objc/RuntimeUtils.java

  Line 836 in 473221a

  val = new Integer(Integer.parseInt((String)val)).shortValue();

  
  This should very likely use Short.valueOf(String) (see also Remove redundant primitive boxing in RuntimeUtils.getAsReferenceWrapper(...) #29)
• There are multiple cases where an instanceof Number call is made and afterwards the respective primitiveValue() is called, e.g.:
  

  Java-Objective-C-Bridge/src/main/java/ca/weblite/objc/RuntimeUtils.java

  Line 822 in 473221a

  val = ((Number)val).intValue();

  
  This can cause precision loss when the argument is of type Number but is a larger type or conversion from floating point to integer type is performed, e.g. Double -> Integer
  Not sure if this can be easily made safer without breaking backward compability.
