JFileChooser Problem in 1.4 ?

[Ingo Proetel]

Hi,

I tried an application that works fine on jdk 1.3.1 with the jdk 1.4.0.
It seems every time I try to instanciate a JFileChooser I get the
following NullPointerException:

java.lang.NullPointerException
at sun.awt.shell.Win32ShellFolder.getChildByPath(Win32ShellFolder.java:570)

This happens independent of which constructor I use.
Has anybody seen this also ?

JFIleChooser is a horlix, especially in 1.4. Send a bug report to sun about
it, there it will join a host of others that don't get fixed!
Try selecting 100 files in it at once, then go and have a cup of tea and
come back to see if it's returned yet!
