Regression : 4901731 encoder test passing with 142_10-b03 but failing with 142_11-b01

Synopsis : encoder test passing with 142_10-b03 but failing with 142_11-b01

Test Case :
===========
CTE_REGTEST/Generic/4901731/encoder.java

uname -a :
========
SunOS urti059 5.10 Generic_118844-22 i86pc i386 i86pc

                            Assembled 25 October 2005

java -version
=============
java version "1.4.2_11-ea"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_11-ea-b01)
Java HotSpot(TM) Client VM (build 1.4.2_11-ea-b01, mixed mode)

To Reproduce:
=============
install jdk in the testing machine
copy the encoder.java in the testing machine ( encoder.java Attached to the bugster)
compile the encoder.java file
excute the java file by using the command <java_home>/bin/java -Xms300m -Xmx512m encoder (according to README file attached to the bugster)

OUTPUT :
=======
took 1: 180
Write - Passed
