Hello,

I tried to launch a Java 1.4 Swing application on Citrix MF, not using
the installed JRE 1.5, but using a JRE 1.4.2, bundled in a subdirectory
of my application by just invoking the javaw.exe. With JRE 1.3.x this
works fine, but with the 1.4 version I get always
java.lang.NullPointerExceptions from the constructors of various
Swing-element, such as

java.lang.NullPointerException
at javax.swing.border.EmptyBorder.<init>(Unknown Source)
at
com.sun.java.swing.plaf.windows.WindowsTableHeaderUI$XPDefaultRenderer.getTableCellRendererComponent
...

I've searched the groups, but this seems to be a little-known problem.

Any help would be appreciated.

Max
