Java version mismatch in org.eclipse.jdt.compiler.tool bundle? [message #248368]

Hello everyone,

On my Linux platform in which I have Eclipse 3.3 installed, I am seeing
periodic failures when I run test workbenches in the resolution of the
bundle "org.eclipse.jdt.compiler.tool_1.0.0.v_771". Upon examining this
plug-in's MANIFEST.MF file, I find that it has a
RequiredExecutionEnvironment of "JavaSE-1.6". This would seem to directly
conflict with the assertion on the main Eclipse download page that the "Java
5 JRE is recommended" for europa downloads. I obviously only have Java 5
(JRE 1.5.0_12) installed.

Any thoughts on this?

-Pete

Pete,

I guess the respective bundles/fragments contribute optional
functionality that makes only sense if you're running a 1.6 JRE.
It doesn't require you to actually have a 1.6 JRE but when you have it
you can use its features (like APT).

Cheers

JRE 1.5 is fine if you don't use 6.0 features.
org.eclipse.jdt.compiler.tool and org.eclipse.jdt.compiler.apt are about
the jsr199 and the jsr269 which both require a JRE1.6. This is why are
are not resolved if you only use a JRE1.5.
This will not prevent you from using Eclipse.
Hope this clarify the error.

Olivier and Eike's explanations are correct.

For more info on the underlying issue of how plugins indicate failure to
load, see (and vote for, if you choose)
