In general makes sense. I would not add anything to
I assume you might want either update that
which has no need to have any "workspace" relationship. |

@iloveeclipse thanks for feedback. The problem with JavaCore.run is that this does tons of other things because it is meant to be used for write operation. How about JavaCore.runRead(Runnable)? |
|
or JavaCore.call(JavaCallable) like org.eclipse.swt.widgets.Display.syncCall(SwtCallable<T, E>) |
|
the call hierarchy view is a bit more complicated: i don't see jdt.ui in the callstack around the sort: |
|
the first time JDTs callstack is more usefull - CallHierarchyViewer could be overloaded: |

Could this also help to speed up PDE's search for unused dependency (in the MANIFEST-Editor's dependency tab)? |
May be, please try it out. It should be pretty simple to just add JavaCore.run() in the outermost PDE Class in the stacktrace of the problem |

The first time I try to open a class with an F3, after I restart Eclipse, the editor cannot open due to this exception stack trace: I tried to open The editor with My Eclipse SDK is: My workspace is very old, I have been re-using it for years now. I don't know if that makes a difference either. @jukzi sorry I've not been follwing the JDT tracker. If there is an issue for this bug, sorry for the noise. |

Currently performing UI Operations like a "fast" type hierarchy can be kinda slow. By example for
java.lang.Object.Sampling i see most time is spend on opening binary JARs. Debugging that i see the same Zip files are opened again and again. JDT CORE already has an internal mechanism to prevent that:
org.eclipse.jdt.internal.core.JavaModelManager.cacheZipFiles(Object).However there is no way to use that in jdt.ui. Example stacktrace:
The loop is in the UI and there is not CORE code around it - only jdt ui code.
As a proof of concept i added the internal cacheZipFiles() call around
org.eclipse.jdt.internal.ui.typehierarchy.HierarchyInformationControl.setInput(Object)andorg.eclipse.jdt.internal.core.SearchableEnvironment.SearchableEnvironment(JavaProject, ICompilationUnit[], boolean)Which results in the time spend in org.eclipse.jdt.internal.core.JavaModelManager.getZipFile () is reduced from 48seconds to 40ms - more then thousand times faster! (SWT then becomes the bottle neck)
Any objection that JDT provides public API like
org.eclipse.jdt.core.IJavaModel.runBatch(Runnable)?Other suggestions for the naming? @iloveeclipse @jjohnstn
