JDK : JDK1.4.2-b02
Testbase : RegTest-test
Platform[s] : RedHat Linux 7.2 (GNOME), Windows XP Home, Solaris 9 (sparc) (GNOME), Solaris 8 (x86)
Falling test[s]:
        java/awt/Graphics/DisposeTest/DisposeNOP.java

java/awt/Graphics/DisposeTest/DisposeNOP.java fails on JDK1.4.2-b02.
The test passed on JDK1.4.1-b21.
This happens because the code related to sun.java2d.SunGraphics2D.dispose method
was changed in JDK1.4.2. A new class sun.java2d.NullSurfaceData was introduced
in JDK1.4.2 and its getRaster method contain the following code
        throw new InternalError("obsolete interface used");
which leads to the failure.

It worth to note that although the Java API specification requires that
"A Graphics object cannot be used after dispose has been called", the test
was written in response to the customer call (bugid 4107389):

"We've got a slight inconsistency in our code when a Graphics object is
used after a dispose. The Javadoc comment indicate that the Graphics
object should not be used after a dipose BUT the Class Libraries book
suggests that operations are ignored after a dispose."

Also note that getRaster throws an Error and it is not caught by the test.
As a result the test fails immediately under JavaTest, but runs infinitely
when it is stated with the shell script provided below.

How to reproduce:
=================
Run the following script (you may need to change its variables as needed)
 
--- script start ---

#!/bin/bash

PS=':'
JDK=/net/linux-15/export/home/java/jdk1.4.2/linux
TEST_BASE=/net/linux-15/export/home/java/regtest
TEST_PACKAGE=java/awt/Graphics/DisposeTest
TEST_SHORT_NAME=DisposeNOP
TEST_NAME=$TEST_PACKAGE/$TEST_SHORT_NAME

TEST_SRC=$TEST_BASE/test/${TEST_NAME}.java

export CLASSPATH=.${PS}${JDK}${PS}${JDK}/lib/tools.jar${PS}${TEST_BASE}${PS}${TEST_BASE}/test/${TEST_PACKAGE}

$JDK/bin/javac -g -classpath $CLASSPATH -d . $TEST_SRC

echo "$JDK/bin/java -cp $CLASSPATH $TEST_SHORT"

$JDK/bin/java -cp $CLASSPATH $TEST_SHORT_NAME

--- script end ---
