I read the announcement of 6.0GA in the announcement forum. Among others the text said:

You’ll need a fresh Eclipse 3.3 SDK installation and JDK 1.5.0_08+ on Windows or Mac, and *only* JDK 1.5 on Linux

So I take it JDK 6 is not supported on Linux. Is there any reason for that? What problems would I likely run in to if I used JDK 6 on Linux anyway?

henk,
We still have some wonkiness with M4M (and I believe UML) with Java 6, but it’s not show-stopping, and if you aren’t using those features I think for the most part MyEclipse runs pretty well with Java 6. You could certainly spin it up with it. If you run into some strange behavior back it back down to 1.5.0_12 and see if that fixes it.

Ok, thanks. I heard of another developer who encountered some NPEs using MyEclipse 6M1/Java 6U1 on Linux (Debian Lenny). After he has updated to 6.0GA and still runs into these NPEs, I’ll try to see if 1.5 helps and report back to you. I’m sure though he’s not using M4M or UML.

I’m using ME6M1/jdk1.6.0_02/64-bit eclipse on RedHat Enterprise Linux 5. Runs fairly well – crashes about once a day. I’ve tried to upgrade to ME6GA on a jdk1.5/eclipse32-bit, but it complains about conflicts using the subclipse – which is crucial for me. No experience w/ the UML.

John,
What’s the conplaint about Subclipse?

[jccartwright]

When I try to install subclipse, I select the core product, accept the license, and am then presented with a dialog:
“If you want to continue with the update/install, the resulting configuration will contain duplication conflicts that may cause parts of the product to be unusable. Do you want to continue?”

The conflicts include Eclipse XML Editors and Tools, J2EE Standard Tools (JST) Project, JST Common Core, JST Enterprise Core, and several others. The conflicting files are named “Version 2.0.0.v200706182145…” and “Version 2.0.0.zmyeclipse60020070820”

I inferred from one of the other threads that these warnings could safely be ignored – is that true. Should I install subclipse before installing ME?

Thanks!

John,
Normally duplicate issues can be ignored, but I’m confused why Subclipse would be telling you it was running into conflicts with XML Editors, JST* and so on…

I’d suggest give it a try and see how things work. The worst case scenario you could reinstall MyEclipse and continue with the workspace.

NOTE: I use subclipse with my MyEclipse 6.0 GA install as well as a few other developers in house and I’ve never seen this warning before. It’s possible you don’t have a clean MyEclipse install going.

[jccartwright]

Thanks for your reply Riyad. No It doesn’t make sense to me either but I don’t know how to get a “cleaner” install. The MacOS X installer doesn’t work on my machine, so I did a new ME manual install into a new Eclipse 3.3 J2EE install with a new workspace.
