[Bug swing/27407] New: NullPointerException in javax.swing.text.WrappedPlainView$WrappedLine.getPreferredSpan()

[pere at hungry dot com]

When running openjump in debian/unstable using jamvm and the CVS
version of classpath, I get a NullPointException in
javax.swing.text.WrappedPlainView$WrappedLine.getPreferredSpan(WrappedPlainView.java:521)
when selecting 'Help->About' from the meny.

This is the output from an example run.  The JDOM exception is from
the start of the program, but do not seem to be fatal.  The
NullPointerException is at the end.  After trying the About menu entry
I exited the program and it ended normally.
