4507053: Javadoc hangs when '}' is missing from inline tag

For build 83, of Merlin
=======================

for the following testcase (to verify 4507053)
Notice '}' is missing.
--------------------------

jtools-sqe:/home/vr128054/vertest/4507053 132 % more t.java
/**
 * {@link test.html
 * @author Vijayan Reddy
 * to Catch a BUG
 */

{
}

the following dump is obtained, with 4 warnings reported on the same line (repetitive warnings too).

==========================================================
This is the description from the duplicate bug 4513377:

The following doc comment creates three warnings for the first missing '}'
on @link, and no warnings for the second missing '}' on @docRoot:

/**
 * {@link com.package1.Class1#publicStaticMethod().
 * Any label would be ignored.
 *
 * @see <a href="{@docRoot/com/package1/Class1.html">Class1</a>
 */

Here are the warnings:
./Class1.java:34: warning - Missing closing } character for inline tag: "{@link com.package1.Class1#publicStaticMethod().
 Any label would be ignored."
./Class1.java:34: warning - Missing closing } character for inline tag: "{@link com.package1.Class1#publicStaticMethod().
 Any label would be ignored."
./Class1.java:34: warning - Missing closing } character for inline tag: "{@link com.package1.Class1#publicStaticMethod().
 Any label would be ignored."

This is a simplification of the the full class Class1.java, which is attached.
