I think that match() doesn't work due to bug #4137.
I've verified that the problem is gone when suggested fix for 4137 applied.

But after this I get exception in subst()
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String ind
ex out of range: -1
        at java.lang.String.substring(String.java:1480)
        at org.apache.regexp.RE.subst(RE.java:1784)
        at Bug25985.main(Bug25985.java:9)
It occured because we specify RE.REPLACE_BACKREFERENCES flag for subst(), but 
substitution parameter dosn't contain any such references.  Thus we try to 
execute the following line:
                // Append everything after the last $ sign
                ret.append(substitution.substring(lLastPosition+2,lLength));
when lLength == 1 and lLastPosition == 0 (so, start position more then end one)
To fix this problem we can just change default value of lLastPosition to -2
(so if there is no $ in substitution param we will add substitution itself)
