While trying out a Java program, I noticed that some BadValue X errors
were being reported (I had to set -Dsun.awt.noisyerrorhandler=True
first). The webrev at
attempts to fix the issue.
The problem is that there are some cases where the jdk is creating or
resizing windows and setting widths and/or heights to 0. The man page
for XResizeWindow states "If either width or height is zero, a BadValue
error results". I looked at the source code for xorg-xserver and it
appears that specifying a height or width of 0 for pretty much any X
call will cause a BadValue error.
The patch takes an approach similar to what is currently being done in
XBaseWindow.xSetBounds(). It checks heights and widths, setting them to
1 if needed.
