Moving aside my …/.metadata/.plugins/org.eclipse.core.runtime/.settings fixes the issue. In using opensnoop (dtrace tool to dump file opens), something happens to cause the workbench.xmi file to be loaded a bit sooner. < /.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.core.resources.prefs < /.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.workbench.prefs < /.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.egit.core.prefs < /.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi 314,315c313,314 < /.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.launching.prefs < /.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.ui.prefs --- > /.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
org.eclipse.core.resources.prefs seems to be the culprit. It contains: ———————————- eclipse.preferences.version=1 encoding=UTF-8 refresh.enabled=true version=1 ———————————- So indeed the FSEvents-based file refresher from comment 3 does seem to have been the culprit. A pity! Closing as NOT_ECLIPSE.
