The Execution Environment that is set on the plug-in manifest governs
the lowest JRE version the plug-in can work with. If the OSGi runtime
(equinox) is running with a lower JRE than the plug-in will not be
So marked the EE carefully to the lowest JRE you wish to support.
Similarly, ensure the Java compliance level matches the EE.
For example, assume the EE is set to J2SE-1.4 and the Java compliance to 1.5. Now, if you use annotations, the code would still compile in your workspace. However, when deploying, the plug-in would fail it will tell OSGi that it can run with 1.4 but actually it can not.
