12/4/99 eval1127@eng -- still an issue as of kestrel RA (1.3.0 build "I").  (Bug 4242173 seemed to suggest this might have been fixed by now.)

java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-O)
Java(TM) HotSpot Client VM (build 1.3beta-O, mixed mode)

The parseInt() method of the Integer primitive wrapper class does not recognize
a unary plus as a parseable character.  This code:
<p><pre>
        String deltaString = "+93";
        int delta = Integer.parseInt(deltaString);
</pre><p>
throws the following exception:
<p></pre>
        java.lang.NumberFormatException: +93
	      at java.lang.Integer.parseInt(Integer.java:409)
	      at java.lang.Integer.parseInt(Integer.java:458)
</pre><p>
The code for Integer.parseInt() contains this fragment:
<p><pre>
		digit = Character.digit(s.charAt(i++),radix);
		if (digit < 0) {
		    throw new NumberFormatException(s)
</pre><p>
which will cause the above exception.  The code looks for the minus sign and
bumps the parsing index up; it should also include a test for a plus sign.

Integer.parseInt does not handle strings like "+123".
While this appears to be deliberate (and therefore not a bug)
I think it is silly.  Why not allow it to handle explicit positives?

Integer.parseInt("123") ;   // works
Integer.parseInt("-123");   // works
Integer.parseInt("+123");   // throws NumberFormatException
