while working with e4 I realized, that org.eclipse.e4.ui.workbench.renderers.swt.HandledContributionItem.updateItemEnablement() is called about once a second for every ToolItem in my MainToolbar. This leads to HandledContributionItem.updateIcons(). I think this call is needed here to switch between enabled/disabled icons. But even if there is no change the icon bytes are requested via iconURI and a new SWT Image is created everytime.
A similar problem exists for the labels and tooltips, which are newly translated via TranslationService on every updateItemEnablement-call.
Is this a bug? Or required by some reason I don't see yet?
