Troubles while migrate Eclipse Luna projects from 32 bit to 64 bit

Question

could you help me to fix a problem?

I worked on Eclipse Luna until recently and all my e4 projects worked well under Linux x86 (JDK7 and Eclipse were by 32 arch too). Now I migrate to a newer computer with Linux 64 bit. I install both JDK7 either Eclipse Luna 64 bit. But I can't run my RCP application. Got many error like this:

!ENTRY org.eclipse.e4.ui.workbench 4 0 2015-07-26 15:22:26.571 !MESSAGE Event Admin service is not available, unable to publish event org.osgi.service.event.Event [topic=org/eclipse/e4/ui/model/ui/Context/context/SET].

and so on...

What does it mean and how to fix it? I created my projects on 4.x Eclipse version.

What I tried:

• to put projects to a fresh workspace
• to clear and remake Eclipse product dependences

But I got the same errors

Answer 1

I've fixed it. Added org.eclipse.equinox.event bundle into Required Plug-ins section of my launcher. And also added it to Product dependences. Everything worked out.
