Migrate RCP from 4.4.2 to 4.16 [message #1840592]

I am new to Eclipse RCP development. We have a legacy RCP which was developed using 4.4.2. We now have a need to upgrade as there are a few third party libraries that are vulnerable. I have two part question;

1. Can we upgrade only the third party jars that are consumed by equinox core which are vulnerable?
2. How do I migrate my RCP from 4.4.2 to higher version like 4.16 (this is the last version that works with JRE 1.8).

Any guidance on this is greatly appreciated.

Your questions don't really have generic answers. Bundles typically specify dependencies using lower and upper bounds so a newer version of some bundle might specify a lower bound that makes it not compatible with a older version of Eclipse (because it uses a new API not available in an older Eclipse). You can only try and see .

What if anything needs to be migrated depends on what you use. You might find that everything you use is still available in the newer version of Eclipse and that there is nothing to migrate. Again, you can only try and see...

There appear to be porting guides like this:

where you can replace the "20" with whatever version....

Ed,

Thanks for the reply. Let me ask a different question. Is it possible to just update a single third party jar from the eclipse sdk that is used to build my RCP?

Specifically, I am looking to replace "plugins/org.eclipse.jetty.http_8.1.16.v20140903.jar" with "plugins/org.eclipse.jetty.http_9.4.11.v20180605.jar" from the "eclipse-SDK-4.4.2-win32.zip"?

Thanks in advance.

It's likely difficult to update a single jar, and certainly you can't just replace it in the file system because the "profile" expects a certain version to be present. Also, features typically include bundles and then that restricts the version to be a very specific one. So generally a replacement requires doing an actual update to install newer replacements.
