While playing around with some Swing features, I get this message:

The following exception is thrown when jsconductor is executed:

A nonfatal internal JIT (3.00.078(x)) error 'Unuse' has occurred in : 'COM/sun/suntest/javascope/gui/O0981/O01003.<init> (LCOM/sun/suntest/javascope/gui/O0981/O0985;)V': Interpreting method.

However, the tool seems to instrument the java file successfully i.e. it compiles and
the javascope browser is able to read it.

My program hangs during execution and causes a java.lang.NoClassDefFoundError.

However, I'm not sure if this error is related. So I have produced a seperate bug
report for it.

The following is the jdk version information

-version
java version "1.2"
Classic VM (build JDK-1.2-V, native threads)

-fullversion
java full version "JDK-1.2-V"

My CLASSPATH reads :

CLASSPATH=.;c:\javascope\JavaScope.zip

I get the error:
A nonfatal internal JIT (3.00.078(x)) error 'Unuse' has occurred in :
  'ZJeffVectoredFrame.placeComponents ()V': Interpreting method.
  Please report this error in detail to http://java.sun.com/cgi-bin/bugreport.cgi

The block of code that seems to generate it is:
JPanel paramPanel[] = new JPanel[ 13 ];
JLabel paramLabel[] = new JLabel[ 13 ];
JTextField paramField[] = new JTextField[ 13 ];
JPanel paramFieldPanel[] = new JPanel[ 13 ];

//Labels & Fields
for( int i=0;i<=12;i++)
{
paramPanel[i] = new JPanel();
paramPanel[i].setLayout( new BoxLayout( paramPanel[i], BoxLayout.Y_AXIS ) );
paramLabel[i] = new JLabel( "Param" + i );
paramPanel[i].add( paramLabel[i] );
paramField[i] = new JTextField( FIELD_WIDTH );
paramFieldPanel[i] = new JPanel();
paramFieldPanel[i].add( paramField[i] );
paramPanel[i].add( paramFieldPanel[i] );
}

If I comment out the BoxLayout, or if I don't add more than one thing, it doesn't give the error.
The total source of this application is only about 300 lines, and so not much can go wrong.
Especially since almost all of it is copied out of something that works fine.

If you care to see more, I can send you the whole source and let you deal with it.
I have a huge program that hasn't even gotten to alpha, and final is due in October.
