OPERATING SYSTEM
----------------
All

FULL JDK VERSION
----------------
All (reproducible with 1.4.2, 5.0, 6 and 7)

PROBLEM DESCRIPTION
-------------------
Under certain circumstances a hyperlink in a JEditorPane can be opened by clicking in blank space near the link, rather than on the link. This even happens when the mouse pointer does not indicate that clicking will open the link, so it is counter-intuitive.

The problem occurs only when a hyperlink is the first item in a HTML paragraph. It does not occur if the link is not the first content contained within a set of <p> tags, for example:

"First link as para <p>extra text<a href='http://www.google.com/&#39;&gt;Para&lt;/a&gt;&lt;/p> "

or if it is not enclosed in <p> tags at all:

"First link as para <a href='http://www.google.com/&#39;&gt;Para&lt;/a>"

REPRODUCTION INSTRUCTIONS
-------------------------
1. Compile and run the attached testcase
2. Observe a fram containing a line of text, and a hyperlink below it.
3. Click the empty space between the text and hyperlink. Observe that
   the link is opened, even though the link itself was not clicked.
