I think the bug should be reopened: it was about the syntax on < and >
rather than the fontification.

If you put point in front of any of the <s, you should be able to
execute C-M-f, moving to the matching >.

This doesn't happen in the current scenario because the closing >s,
written without intervening spaces, get confused with the Java shift
right operator ">>>".  If you insert a space into that triplet, the
syntax comes back again.

This will be easy to fix.
