Geting java.awt.AWTError: Can't connect to X11 window server on HP-unix with JRE-8

on running the GUI based java application using JRE 8 on HP-UX I am getting the following error:

Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using 'ravkumar-t430.apac.tibco.com:1.0' as the value of the DISPLAY variable.

But once I use the JRE 7 instead of JRE 8 then issue resolves and application comes up fine.

When I set the java.awt.headless=true property in the application then it gives the java.awt.headless exception.

Please suggest me the solution.

Solution

It's a bug in the HP-UX operating system which creates issues with X11 displays with 64 bit JRE. This issue is resolved after installing the latest OS patch PHSS_43291.

There are two solutions to this issue:

1/ Either switch to 32 bit jre

2/ Install latest patch on 11.31.
