Markus Keller wrote up an nice summary of what consumers should do to fix any warnings that may be caused by this change at https://bugs.eclipse.org/bugs/show_bug.cgi?id=442021#c25
Here is a copy of the recommendations if you are going to compile against the latest version of org.eclipse.equinox.common:
1. In MANIFEST.MF, update your Require-Bundle: org.eclipse.core.runtime;bundle-version="[3.11.0,4.0.0)", or org.eclipse.equinox.common;bundle-version="[3.7.0,4.0.0)", or update your Import-Package: org.eclipse.core.runtime; version="[3.5,4.0)"
2. If your bundle re-exports one of these bundles, then you also have to make sure the minor version is incremented.
3. Remove unnecessary casts (Clean Up, or Problems view > Quick Fix > Select All)
4. Update implementations of IAdaptable#getAdapter(Class<T>), unless you override another implementation of that method that still uses the old signature.
Typical change:
Old:
{code}
public Object getAdapter(Class adapter) {
if (ICompilationUnit.class.equals(adapter))
return getCompilationUnit();
return null;
}
{code}
New:
{code}
public <T> T getAdapter(Class<T> adapter) {
if (ICompilationUnit.class.equals(adapter))
return adapter.cast(getCompilationUnit());
return null;
}
{code}
5. Update implementations of IAdapterFactory
Hint for 4. & 5.:
- Open Type Hierarchy on IAdaptable, etc.
- In the view menu, select a working set that contains your projects
- In the methods list of the Type Hierarchy view, select the methods, and then click the first toolbar button (Lock View and Show Members in Hierarchy)
