We (Dali) adapt the platform interface IProject to the Dali interface ProjectResourceLocator.
This Dali interface and its sole implementation, SimpleProjectResourceLocator, are in the plug-in o.e.jpt.common.core. The IAdapterFactory that implements this "adaptation" is in the same plug-in. And plugin.xml defining the corresponding extension to the o.e.core.runtime.adapters extension point is also in the same plug-in.
The problem: Intermittently, during start-up, a call to IProject.getAdapter(ProjectResourceLocator.class) will return null with the first call but not null with subsequent calls. The adapter factory is implemented in such a way that it will never return null; so, apparently, the adapter factory is not invoked by the platform adapter manager. This seems to be a bug, as the plug-in must have been loaded for the class ProjectResourceLocator to be resolved. Unfortunately, in a test workspace where this happens with every start-up, it never happens when executing under the debugger (even with no breakpoints whatsoever).
Is this expected behavior (i.e. that even though a plug-in is loaded, its adapter factories are not necessarily loaded)? If not, can anyone offer any hints as to how we can investigate, sans the debugger, why the platform adapter manager does not invoke the appropriate adapter factory?

Hi,
I have start a plugin and I try to remove one element from the team synchronize view
(like when right clic and choose => remove from view)
but with my code I only remove from the tree not from the entire view
someone can help
IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);
IWorkbenchPart activPart = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActivePart();
if(activPart instanceof SynchronizeView){
SynchronizeView syncView = (SynchronizeView)activPart;
TreeViewer tv = (TreeViewer) ((ISynchronizePage)syncView.getCurrentPage()).getViewer();
tv.expandAll();
SynchronizeViewWorkbenchPart synchPart = new SynchronizeViewWorkbenchPart(syncView.getParticipant(), syncView.getSite());
tv.setSelection(new StructuredSelection(), true);
tv.addFilter(new ViewerFilter() {
@Override
public boolean select(Viewer arg0, Object arg1, Object arg2) {
String elem = arg2.toString();
if(elem.endsWith(".classpath") || elem.endsWith(".project")){
return false;
}
return true;
}});
}

Does anyone know how to specify what jvm eclipse will launch itself with when it switches workspace? If I start eclipse with an eclipse.ini containing:
-vm
Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk/Contents/Home/bin/java
eclipse launches with that jre. The console output confirms this:
5/14/13 4:01:16.932 PM [0x0-0x51b51b].org.eclipse.eclipse:
eclipse.buildId=M20130204-1200 5/14/13 4:01:16.932 PM
[0x0-0x51b51b].org.eclipse.eclipse: java.version=1.7.0_17
5/14/13 4:01:16.932 PM [0x0-0x51b51b].org.eclipse.eclipse: java.vendor=Oracle
Corporation
When I switch the workspace though for some reason it launches itself with a 1.6 jvm.
5/14/13 4:07:51.596 PM [0x0-0x51b51b].org.eclipse.eclipse: eclipse.buildId=M20130204-1200
5/14/13 4:07:51.597 PM [0x0-0x51b51b].org.eclipse.eclipse: java.version=1.6.0_45
5/14/13 4:07:51.597 PM [0x0-0x51b51b].org.eclipse.eclipse: java.vendor=Apple Inc.
This is a problem as our plugins that require 1.7 consquently fail to load. This is on OSX 10.7.5 but it also happens on 10.8.
JAVA_HOME points to the 1.7 jvm and /usr/bin/java is also symlinked to the 1.7 jvm. /usr/bin appears near the head of my PATH and in fact its the only java on my path. I'm guessing that eclipse must assume that the "best" jvm is the one in /System/Library/Frameworks/JavaVM.framework/Versions/Current or /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK and that points 1.6.
thanks,
Nick

Hi,
I have implemented WorkbenchWindowControlContribution contributing to toolbar:org.eclipse.ui.trim.status (it's just a label displaying a text).
I would like to change the text of the contribution when user presses some button.
I can't figure out how link the contribution with the view.
I have tried to override the setWorkbenchWindow handler of the WorkbenchWindowControlContribution but when it is called my view is not created yet so I can't register any listeners that the contribution could listen to.
Any suggestion?
Regards,
Janusz
