class X
{
public void x ()
{
for (int this_is_not_a_function_name : getX ()) {
}
}
}
In current trunk (compiled five minutes ago) 'this_is_not_a_function_name'
above is fontified as a function name. This seems to depend on whether I
have '()' after 'getX' or not.

I have a potential solution for this bug, as it has impacted me as well.
Not sure what the best solution would be but I have included a patch that does solve the problem. From what I can tell there are no tests for java fortification but I have not seen any issues arising in my own java projects. The issue was that in java, a “:” can mark the end of a declaration in a foreach, not just a “;” or “,”.

I missed this bug report back in 2014. The code has moved around so
much since then that Jordon's patch no longer applies. But a simple
patch with the same idea appears to fix this bug:

This patch should apply cleanly to the emacs-27 branch, and most
probably to master, too.

Thanks for taking a look.
With your fix, applied on the master branch, in the example given:
class X
{
public void x ()
{
for (int this_is_not_a_function_name : getX ()) {
}
}
}
The "int" no longer has font-lock-type-face. Should it?

Stefan Kangas

That's funny. It has font-lock-type-face for me, in all of emacs-27,
master and standalone CC Mode (in master). font-lock-type-face is indeed
correct, here.
Are you sure you were .... (I don't think I need to fill in the dots for
you. ;-)

Hello, all.
I've committed a fix to this bug to the emacs-27 branch at savannah.
I'm closing the bug with this post.
