Re: [epp-dev] Missing or wrong osgi.requiredJavaVersion
Hi Eike,

thanks for the reminder, I think we need to revisit this setting again. We've had a longer discussion during the Luna development cycle, and it wasn't possible to use the same requirements for all packages, but reasoning seems to have changed this year with Mars.

I've opened bug 464771 [1] for Mars.

AFAIK, the Eclipse Platform never required a certain Java level with osgi.requiredJavaVersion, and that is probably the correct decision because their deliverables are more targeted at the developer (and not at the end-use) who can be expected to have a good understanding of the internals.

Thanks,
Markus

Hi,

It seems that the Platform has started to require Java 1.7 in some of the core bundles (e.g. core.contenttype), which implies that all Mars packages should ship with p2 touchpoint instructions that add -Dosgi.requiredJavaVersion=1.7 to the eclipse.ini files. But that doesn't seem to be the case. If I'm not mistaken the following packages still specify their products with a pre-1.7 Java requirement:

    - modeling
    - reporting
    - jee
    - java
    - dsl

BTW., the Platform itself doesn't seem to specify respective touchpoint instructions at all:

    <unit id='toolingorg.eclipse.sdk.ide.ini.win32.win32.x86_64' version='4.5.0.I20150320-0800' singleton='false'>
