Eclipse complaining about Javadoc even after Disabling javadoc in compiler
options, and inconsistent

I've got some open source code using the {@Code annotation that Eclipse is
complaining about. Since I don't care I turned off Javadoc in the compiler
options, but it's still complaining and will not compile compile.
Error is: "Javadoc: Missing closing brace for inline tag"
Actually the closing brace IS present. In some cases it's just a few lines
down, but in others it's even on the same line!
Even stranger: The same code in a smaller project in a different workspace
works OK. I've compared the 2 projects' settings a couple times and they
appear to be the same. In many cases options are set to not allow project
specific settings.
I also did other things like doing a project clean, and trying Java 1.5
vs. 1.7 compiler options, etc.
Other details:
Java 7 on Mac
Eclipse Kepler
Code is Guice 2.0 (I know that's old, and normally should use jar, long
story)
one example is Key.java line 107, see below
Example from Guice code (though I normally wouldn't care since it's just
comments)
/**
...
* <p>{@code new Key<Foo>() {}}.
