Dispose of JDialog doesn't work

[tbergstedt]

Being quite new to Java, I am trying to make the simplest form of user input with JOptionPane.showInputDialog (I know it's not recommended, but I don't want to get into custom-made dialogs just yet). All input works fine, but the program doesn't seem to release the threads to the dialogues, resulting in the program hanging at the end of execution.

Here's the code:

JDialog dialog = new JDialog();
tmpAnswer = JOptionPane.showInputDialog (dialog, "Enter new revision");

dialog.hide();
dialog.dispose();




I thought the call to dispose should release threads made to the dialog, but doesn't seem to work. Could somebody tell me what I have done wrong?

Here's the result from a jdb thread call:
