ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
There is a difference in handling "-cp" option in java.exe and javaw.exe with wildcard.
We can add all jar files in a directory to classpath using wildcard option. But this works only while using java.exe. Wildcard does not work in javaw.exe
Suppose C:\Temp\lib contains two jar files a.jar and b.jar ,then we can use wildcard while specifying classpath.

e.g.
java -cp C:\Temp\lib\* javaprogramname
When java.exe all the jars inside C:\Temp\lib are added to classpath.

javaw -cp C:\Temp\lib\* javaprogramname
When using javaw.exe jars inside C:\Temp\lib are NOT added to classpath.






STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Suppose C:\Temp\lib contains two jar files a.jar and b.jar

Then run the following program with java and javaw.

java -cp .;c:\Temp\lib\* ClassPathTest
This gives output as ".;c:\Temp\lib\a.jar;c:\Temp\lib\b.jar"
This is correct behaviour.

javaw -cp .;c:\Temp\lib\* ClassPathTest
This gives output as ".;C:\Temp\lib\*"
This is wrong behaviour. Wildcard options is ignored.


ClassPathTest.java
-----------------------------------------------------------------------------------------------
import javax.swing.JFrame;
import javax.swing.JTextPane;

public class ClassPathTest {

public static void main(String args[]){
JFrame frame = new JFrame("Test");
JTextPane textpane = new JTextPane();
frame.getContentPane().add(textpane);
textpane.setText(System.getProperty("java.class.path"));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(500,500);
frame.setVisible(true);
}

}

REPRODUCIBILITY :
This bug can be reproduced always.
