Bug 319877 Infinite NPE can fill log file up quickly
Looks like I have ten megabytes worth of logs complaining about this NPE. I would never have noticed if I didn't open up the 'Error Log' view. java.lang.NullPointerException at org.eclipse.e4.ui.workbench.renderers.swt.ToolItemRenderer$7$1.run(ToolItemRenderer.java:378) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.e4.ui.workbench.renderers.swt.ToolItemRenderer$7.run(ToolItemRenderer.java:366) at org.eclipse.swt.widgets.Display.runTimer(Display.java:4167) at org.eclipse.swt.widgets.Display.messageProc(Display.java:3256) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2459) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3655) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$4.run(PartRenderingEngine.java:693) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:618)
