The description from that bug is included below.
Note that I've added the original bug submitter to the
interest list for this bug. If they are external-to-Sun,
then currently there is no easy way for them to update

--------
I am trying to start my application that is deployed on Tomcat on Solaris box
and I always get the error as given below,so my Tomcat never starts without
this error.I am using Jdk1.5.0.2 for my application and have checked my display
setting which is set correctly.
I am not sure if the Xvfb that is available on Solaris box is compatible with
JDK1.5 version.
Can anyone please help me out with this issue.
