Bug 45356 [typing] IndentAction: Pressing Tab at document begin gives IAE
Build 200310150800: Having a multi-line comment starting at document offset 0, the caret as well at offset 0 and pressing tab, the indent action gives an IAE. Reason: The constructor of status called at IndentAction#run() requires a non- null message parameter. The exception that was triggered in the first place results from a taking the previous line of the first one.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/actions/IndentAction.java
private int fCaretOffset;
	
	/** 
	 * Whether this is the action invoked by TAB. When <code>true</code>, indentation behaves 
	 * differently to accomodate normal TAB operation.
