Re: [mdt-papyrus.dev] TR: GMF tooling runtime needs java 1.6+

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi

It might be interesting/essential to make this a general change throughout the Modeling project. For MDT/OCL I would like to move to Java 6 to exploit the new compiler activation API.

MDT/OCL and many other projects are stuck at Java 5 compatibility. I use Java 7 as my development JVM but I find that occasionally when I create new plugins/workspaces I get mysterious bad class file issues. So in my experience, mixing and matching Java 5 and Java 6 may have a variety of confusing opportunities for user problems.

Hi all,

 

For your information, the incoming version of Papyrus will have a stronger requirement on java VM. Since we have re-generated the diagrams between 0.9.0 and SR1, we now have a dependency to the plugin o.e.gmf.tooling.runtime. This plugins includes some annotations new in java 1.6 (override for Interfaces Operations), so Papyrus 0.9.1 needs a VM 1.6+ to run. If there is a lower VM version, Papyrus can be installed, but does not run correctly!

 

I had yesterday  a small exchange with a developer of GMT tooling project. It seems this is possible to ask for a lower vm requirement, for a kind of SR1+ or SR2 version. I do personally think that this would be better to have a quick fix, before SR2 (next February). Some comments can be added to the bug opened in Papyrus bugzilla: (https://bugs.eclipse.org/bugs/show_bug.cgi?id=390444)

 

Cheers,

Rémi

Hi Michael,

 

We are currently using GMF tooling new generators for the Papyrus project. As a consequence, we now depend on the o.e.gmf.tooling.runtime plugin, which requires  a jvm 1.6+.

 

Is this a strong requirement that you have from your partners, or for your own code, to use java 1.6 or is this not mandatory?

Papyrus was requiring, as Eclipse Platform and many of its sub components, only java 1.5. This is a strong demand from our industrial partners, as they have issues to upgrade their java installation (security problems, lack of rights to install anything, etc.).

 

Would it be possible to downgrade your jvm requirements?

 

I tried to have a look on the forums, I found no topics about it.

 

Best regards,

Rémi
