Description
1.4.2_03-b02 on Windows XP A netbeans user encounters a problem very similar to bug 4712307 but also with folders which don't have too many files. See http://www.netbeans.org/issues/show_bug.cgi?id=42079 for information about the bug originally entered against netbeans. It takes tens of seconds to browse directories in file chooser. Thread dump at the moment of 100% CPU utilization for the many seconds shows: "AWT-EventQueue-1" prio=7 tid=0x03512dc8 nid=0xfd8 runnable [689e000..689fd8c] at sun.awt.shell.Win32ShellFolder2.getAttributes0(Native Method) at sun.awt.shell.Win32ShellFolder2.hasAttribute(Win32ShellFolder2.java:405) at sun.awt.shell.Win32ShellFolder2.isDirectory(Win32ShellFolder2.java:442) at sun.awt.shell.Win32ShellFolderManager2.get(Win32ShellFolderManager2.java:193) at sun.awt.shell.ShellFolder.get(ShellFolder.java:245) at com.sun.java.swing.plaf.windows.WindowsFileChooserUI$DirectoryComboBoxModel.addItem(Windo wsFileChooserUI.java:1929) at com.sun.java.swing.plaf.windows.WindowsFileChooserUI$DirectoryComboBoxModel.access$2800(W indowsFileChooserUI.java:1898) at com.sun.java.swing.plaf.windows.WindowsFileChooserUI.doDirectoryChanged(WindowsFileChoose rUI.java:1619) at com.sun.java.swing.plaf.windows.WindowsFileChooserUI.access$3100(WindowsFileChooserUI.jav a:35) at com.sun.java.swing.plaf.windows.WindowsFileChooserUI$15.propertyChange(WindowsFileChooser UI.java:1725) at javax.swing.event.SwingPropertyChangeSupport.firePropertyChange(SwingPropertyChangeSuppor t.java:264) at javax.swing.event.SwingPropertyChangeSupport.firePropertyChange(SwingPropertyChangeSuppor t.java:232) at javax.swing.JComponent.firePropertyChange(JComponent.java:3819) at javax.swing.JFileChooser.setCurrentDirectory(JFileChooser.java:541) at javax.swing.JFileChooser.<init>(JFileChooser.java:321) at javax.swing.JFileChooser.<init>(JFileChooser.java:273) at org.netbeans.beaninfo.editors.FileEditor.createHackedFileChooser(FileEditor.java:372) ... ###@###.### 2004-04-19 ###@###.### 2004-04-20
