due bug in eclipse, every time try change code formatting preferences, eclipse crashes. thus, cannot edit code formatting preferences via eclipse's built in window editor. these workspace specific preferences. can find file edit preferences manually?
it looks code format profiles stored in workspace .metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.ui.prefs file
this java properties format file. code formatter settings in org.eclipse.jdt.ui.formatterprofiles property. value xml object. going hard edit!
