I was investigating what would need to be done to implement camel-case code assist for the Scala plugin when I ran across the following gem in CharOperation (Eclipse JDT):

public static final boolean camelCaseMatch(char[] pattern, int patternStart, int patternEnd, char[] name, int nameStart, int nameEnd, boolean samePartCount) {

	/* !!!!!!!!!! WARNING !!!!!!!!!!
	 * The content of this method has been fully copied to
	 * SearchPattern#camelCaseMatch(String, int, int, String, int, int, boolean).
	 * 
	 * So, if current method is modified, do NOT forget to copy again its content
	 * to SearchPattern corresponding method!
	 */

And in SearchPattern:

public static final boolean camelCaseMatch(String pattern, int patternStart, int patternEnd, String name, int nameStart, int nameEnd, boolean samePartCount) {

	/* !!!!!!!!!! WARNING !!!!!!!!!!
	 * The algorithm of this method has been entirely copied from
	 * CharOperation#camelCaseMatch(char[], int, int, char[], int, int, boolean).
	 * Array lengths have been replaced with call to {@link String#length()} and
	 * array direct access have been replaced with call to {@link String#charAt(int)}.
	 * 
	 * So, do NOT modify this method directly to fix any bug but modify first the
	 * corresponding CharOperation method and do the copy again to be sure that
	 * these two methods are kept synchronized.
	 */

I am sure there is a reason why this was done, but how ugly…

Update: At least JDT made it easy to implement what I wanted.
