[Bug classpath/27189] New: java.text.SimpleDateFormat formats negative time zone offsets with double '-'

[kiyun dot roe at active-endpoints dot com]

java.text.SimpleDateFormat#format() appends a negative sign twice when
formatting a time zone with a negative offset from GMT. For example, using
format string

   yyyy-MM-dd HH:mm:ss Z

should result in something like

   2006-04-14 10:09:39 -0400

in EDT, but it comes out as

   2006-04-14 10:09:39 --400

It appears to me that the culprit is the call to

   withLeadingZeros(hours, 2, buffer);

at about line 812, because hours may be negative.
