A quick fix for the error parsing xml declaration. This is one of the
three outstanding issues in the xml area that must be addressed for the
coming development deadline.
JBS: https://bugs.openjdk.java.net/browse/JDK-8169450
webrev: http://cr.openjdk.java.net/~joehw/jdk9/8169450/webrev/
Checking whether a space follows "<?xml" was sufficient for DOM/SAX for
which the base parser was originally created since the xml declaration
was normalized during version detection. StAX, sharing the base parser
after it was added to the JDK, however, does not use the same version
detection/normalization process and would incorrectly parse the
declaration if there are other whitespaces.
Thanks,
Joe
