This entry is as much a note to myself as it is a hint to the readers of this blog.
I run Linux and not Windows in my environments. In my case, it's currently Fedora 20. I also run RAD (Rational Application Developer) for WebSphere in support of my role on the Portal SEAL team.
If you have installed RAD on Fedora, you have no doubt run into the problem of RAD abnormally terminating. Most times it's a Java return code of "160". This occurs both with RAD 9.0 and RAD 9.1. When you Google for advice, you'll most likely find references to not using "cairo" or "WebKit'. You also see references to the version of xulrunner being wrong.
As some doing, I found the actual answer was tied to the fact that the Eclipse version used by RAD (4.2.2) lacks uptodate classes for WebKit in dealing with recent distributions of Linux like Fedora 19+.
The website that finally gave me the answers I need was this one by Aaron Cohen: "Running RTC, RAD, RSA, or IDA on Fedora 19". However, in order to do what Aaron suggests, you need to download a copy of Eclipse with the fix (4.3+), open the defective RAD jar containing the classes, replace the classes from the downloaded version of Eclipse, the pack the RAD jar back up.
For my own benefit, I've done the work and saved the RAD jar here so that I can get it again. You can untar it into your SDPShared directory that contains "plugins". I've used this fix both on RAD 9.0 and RAD 9.1. I hope it helps you!
