Yes. This is a bug.
If you're interested in what's happening, (you don't have to be ;-):

The problem is to do with CC Mode's suboptimal handling of templates in
C++ Mode and Java Mode.
If you delete the ">=", then type just the ">" (as a first step towards
typing ">="), CC Mode spuriously recognises the "<..>" pair as template
brackets. You can see this with show-paren-mode, or C-M-p.
When you then type the "=", it leaves the "<" as a bracket, but not the
">". This messes up the paren matching, and causes mis-analysis of the
following lines of code.

I can probably fix this quite easily.
Many thanks for a crisp, high quality bug report!
