REGRESSION:sun.io classes are duplicated between rt.jar and charsets.jar

sun/io/CharToByteIS0212_Solaris.class are duplicated in rt.jar and charsets.jar file.

This's regression from 1.4.0_03 to 1.4.0_04 b01 release.

Fix for bug#4765370 in 1.4.0_04 b1 release might cause this regression.

Run the following testcase (test.sh file) with the jdk location as a input parameter
-------------------
#!/bin/ksh

TESTJAVA=$1

rm -f class-list

$TESTJAVA/bin/jar -tf "$TESTJAVA/jre/lib/rt.jar" > class-list 2>&1
$TESTJAVA/bin/jar -tf "$TESTJAVA/jre/lib/charsets.jar" >> class-list 2>&1
$TESTJAVA/bin/jar -tf "$TESTJAVA/jre/lib/ext/localedata.jar" >> class-list 2>&1
duplicates=`grep '\.class$' class-list | sort | uniq -d`

#rm -f class-list
if [ "$duplicates" != "" ]; then
   echo FAILED: $duplicates are duplicated between rt.jar, charsets.jar, and loc
aledata.jar
   exit 1
