Scala 2.7.4-rc1 released Thursday, Apr 16 2009 

Scala 2.7.4-rc1 has been released. It incorporates a few important fixes related to serialization of anonymous functions and generation of Java generics, but the big change is the improved Scala plugin Scala IDE for Eclipse. This means that my backport is now obsolete.

The announcement contains all the juicy information.

Code reuse by copy and paste Friday, Feb 13 2009 

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.
