Description

When extending 'javax.swing.JDialog' and implementing 'show()' JBuilder will incorrectly respond with a deprecation warning as follows:

'"PasswordDialog.java": [deprecation] show() in java.awt.Component has been deprecated at line 44, column 3'

Obviously seeing the Component version of 'show()' instead of the shallower instance in JDialog.

Steps to Reproduce:

Paste following code into Untitled1.java:
----
import javax.swing.JDialog;

public class Untitled1 extends JDialog{
  public Untitled1(){
  }

  public void show(){

  }
}
----
Compile in JBuilder
Compile using javac.

Workarounds

Code compiles and is workable without any extra effort.

The warnings could be confusing, and are certainly annoying for those unlikely to be confused by them.

I cannot reproduce this.  Please provide some additional information:

What JDK are you using?

What compiler and compiler settings are you using?   (under Project Properties | Build | Java )

Where are you seeing this message?  In the message pane or the structure pane?

What is the exact message you get when you compile the example code you posted.  The message given obviously does not match the code.

If you compile your code from the command line with Sun's javac (from the same JDK) compiler, do you see the same messages?

Re-reading my initial post and correlating it to your comment I realize that you meant I used the warning message from my PasswordDialog instead of from the Untitled1 code. I apologize for the confusion wholeheartedly. I should have been more careful in submitting the bug report.

Third try is a charm? Hopefully this attempt will actually post:

All compiler settings are defaults. The JDK is that which is shipped with 2005; java version 1.4.2_04-b05

I see the message as a purple underlined squiggly underneath the methed declarations 'public' flag: eg in:

public void show(){}

On compile, but ONLY IN JBUILDER, I get the message
----------
"Untitled1.java": [deprecation] show() in java.awt.Component has been deprecated at line 6, column 3
There have been deprecation warnings. Please consult the documentation for a better alternative.
----------

Obviously I understand that the message does not match the code; hence the title of this bug report 'Invalid Deprecation Warnings'.

Compiling from the command line using the same JDK gives no warnings.

Here is the exact code (excepting the company name):

package com.xx.temp;
import javax.swing.JDialog;
public class Untitled1 extends JDialog
{
public Untitled1(){ super(); }
public void show(){}
}

cheers,
