Boolean value is inverted when casting

[foaw]

In Casts#castWithPrimitives(...) there seems to be a typo. When converting Number values with boolean.class as the type, it returns true when the given value is 0, and false when the value is 1.

threadtear/core/src/main/java/me/nov/threadtear/util/reflection/Casts.java

Lines 17 to 25 in f0a13d5

	public static Object castWithPrimitives(Class<?> type, Object value) {
	// these values can't be casted from java.lang.Integer
	Object numValue = toNumber(value); // handle Boolean and Character
	if (numValue instanceof Number) {
	Number n = (Number) numValue;
	if (type == short.class) {
	return n.shortValue();
	} else if (type == boolean.class) {
	return n.intValue() == 0;

As of Java 16, Java Virtual Machine Specification says:

The Java Virtual Machine encodes boolean array components using 1 to represent true and 0 to represent false. Where Java programming language boolean values are mapped by compilers to values of Java Virtual Machine type int, the compilers must use the same encoding.

Below I am attaching a list of all calls to this method:

• when converting values on stack in BasicReferenceHandler;
  

  threadtear/core/src/main/java/me/nov/threadtear/analysis/stack/BasicReferenceHandler.java

  Line 65 in f0a13d5

  params[i] = Casts.castWithPrimitives(param, value);

• when building ConstantValue;
  

  threadtear/core/src/main/java/me/nov/threadtear/analysis/stack/ConstantValue.java

  Line 18 in f0a13d5

  value = Casts.castWithPrimitives(int.class, value);

• when updating proxy field values in StringObfuscationStringer
  

  threadtear/core/src/main/java/me/nov/threadtear/execution/stringer/StringObfuscationStringer.java

  Line 162 in f0a13d5

  proxyField.set(null, Casts.castWithPrimitives(proxyField.getType(), stackValue.getValue()));

Not much to fix, but I could send a PR if you want.
