Let's compile JDK with doclint turned on.
We see 2 errors on Path2D class (2D subcomponent):

/export/doclint/jdk/src/share/classes/java/awt/geom/Path2D.java:1931: error: unexpected text
/export/doclint/jdk/src/share/classes/java/awt/geom/Path2D.java:1933: error: unexpected text

Let's look at these two lines:
1931: * {@link Path2D.Float#Path2D.Float(Shape, AffineTransform) Path2D.Float}
1933: * {@link Path2D.Double#Path2D.Double(Shape, AffineTransform) Path2D.Double}

We see that these two lines creates two valid links into overloaded constructor of 2 Path2D subclasses: Path2D.Float and Path2D.Double.

I believe it is wrong behavior and should be fixed.
