It would let you emulate the super(...) call in a language which needs to make a subclass of some Java class with a non-trivial constructor, without forcing the language to generate bytecodes for that subclass's constructor call. It's a pretty small use-case, and the workaround is pretty reasonable: just generate the bytecodes containing the invokespecial call. After all, the number of superclass constructors is much smaller, usually, than the number of overrideable and callable superclass methods. (Generating bytecodes is a burden on very small JVMs, but not elsewhere.) BTW, I just pushed out the first big bundle of Java code changes for the 292 RI, into OpenJDK proper.
