JLS bug (unicode escapes)?

Am I reading this:



A UnicodeMarker seems to be defined as, in regexp terms: "u+" instead of the
expected "u". So, that would mean:

\uuuuuuuuuuuuuuuuuuuuuuu0041  will still turn into "A" just like \u0041
would. What on earth is the thinking behind this?

Amazingly, I tested this in javac and it actually works:
System.out.println("\uuuuuuuu0041"); will print 'A' to stdout. At the very
least the descriptive text in chapter 3.3 should highlight this oddity. Even
ECJ gets this right.

NB: what's the appropriate venue for discussing oddities in the JLS?
