Bug 105816 Extraneous NLS tag incorrectly found in comments
I20050802-0800 In CoolBarManager (org.eclipse.jface) there are NLS tags inside of commented-out blocks of code. These are being reported as compiler errors (when "Usage of non-externalized strings" is set to error). NLS tags inside of commented-out sections should be ignored. If the commented-out sections were uncommented, then the NLS tags would not be errors.
