Attached are new tests for java.io.CharArrayWriter, which
should test it up through the JDK 1.2.2 level.  The results
of these tests with Classpath CVS and Kissme CVS are:

gnu.testlet.java.io.CharArrayWriter.BasicTests
----
PASS: gnu.testlet.java.io.CharArrayWriter.BasicTests: basic string (number 1)
PASS: gnu.testlet.java.io.CharArrayWriter.BasicTests: reset string (number 1)
PASS: gnu.testlet.java.io.CharArrayWriter.BasicTests: flush and close (number 1)
PASS: gnu.testlet.java.io.CharArrayWriter.BasicTests: writeTo (number 1)
0 of 4 tests failed

gnu.testlet.java.io.CharArrayWriter.ProtectedVars
----
PASS: gnu.testlet.java.io.CharArrayWriter.ProtectedVars: count (number 1)
PASS: gnu.testlet.java.io.CharArrayWriter.ProtectedVars: buffer (number 1)
0 of 2 tests failed
