[eclipse-dev] Usage of -dev in the development Eclipse instance

For a long time, PDE had a notion of 'this application' versus 'other
application in the following path' for the target platform. If you want to
selfhost against the platform you are developing on, we reap performance
benefits by initializing our models directly from the live plug-in
registry. This works well in the first instance.

When we launch the second (test) instance, some of the plug-ins in the
registry are in source form, so some PDE functions are affected (classpath
computation, importing binary projects etc.). When testing PDE functions,
we always use 'other application' to avoid this.

Recently we enforced this by disabling 'this application' radio button when
BootLoader.inDevelopmentMode() returns true. However, Nick opened a defect
complaining that he uses '-dev' in his first instance and therefore he
considers this change a regression. Moreover, he claims that there are
other people using '-dev' when launching the first Eclipse instance.

Please add your comments to the defect below to reduce eclipse-dev traffic.
