ConfigurationPropertyName#equals is not symmetric when adapt has removed trailing characters from an element

[Adams112]

Use ConfigurationPropertyName#adapt method to create two ConfigurationPropertyName, a equals to b but b not equals to a

boolean c1 = adapt("demo", '.').equals(adapt("demo$$", '.'));  // true
boolean c2 = adapt("demo$$", '.').equals(adapt("demo", '.'));  // false

The problems is in defaultElementEquals method, see below

private boolean defaultElementEquals(Elements e1, Elements e2, int i) {
		int l1 = e1.getLength(i);
		int l2 = e2.getLength(i);
		boolean indexed1 = e1.getType(i).isIndexed();
		boolean indexed2 = e2.getType(i).isIndexed();
		int i1 = 0;
		int i2 = 0;
		while (i1 < l1) {
                        // at this point, e1 has extra invalid chars, but e2 is end, returned false without cheking
                        // left chars of e1
			if (i2 >= l2) {
				return false;
			}
			char ch1 = indexed1 ? e1.charAt(i, i1) : Character.toLowerCase(e1.charAt(i, i1));
			char ch2 = indexed2 ? e2.charAt(i, i2) : Character.toLowerCase(e2.charAt(i, i2));
			if (!indexed1 && !ElementsParser.isAlphaNumeric(ch1)) {
				i1++;
			}
			else if (!indexed2 && !ElementsParser.isAlphaNumeric(ch2)) {
				i2++;
			}
			else if (ch1 != ch2) {
				return false;
			}
			else {
				i1++;
				i2++;
			}
		}
		if (i2 < l2) {
			if (indexed2) {
				return false;
			}
			do {
				char ch2 = Character.toLowerCase(e2.charAt(i, i2++));
				if (ElementsParser.isAlphaNumeric(ch2)) {
					return false;
				}
			}
			while (i2 < l2);
		}
		return true;
