Output changed from 1.4.5 to 1.5.3 losing closing </li>

[GoogleCodeExporter]

What steps will reproduce the problem?
I'm using antisamy through a plugin in grails:
https://github.com/danieldbower/grails-sanitizer/tree/grails_2_4

This is an unreleased version(0.9) that has updated from antisamy 1.4.5 to 
1.5.3. In my antisamy config, I have

<tag name="li" action="validate"/> 
<allowed-empty-tags>
        <literal-list>
            ...
            <literal value="li"/>
            ...

While running a unit test I found that I was losing </li>

What is the expected output? 
I would expect that I would keep the </li>. This is the same as the input:
<p><span class="font-name-arial font-size-14 underline italic" style="color: 
rgb(198,23,23);">[some text B]</span></p><p><span class="font-name-arial 
font-size-14" style="color: rgb(51,51,51);">some text</span></p><ul><li><span 
class="font-name-arial font-size-14" style="color: rgb(51,51,51);">[some text 
C]</span></li><li><span class="font-name-arial font-size-14" style="color: 
rgb(51,51,51);">[some text C]</span></li></ul>

What do you see instead?
All closing </li> are stripped.
<p><span class="font-name-arial font-size-14 underline italic" style="color: 
rgb(198,23,23);">[some text B]</span></p><p><span class="font-name-arial 
font-size-14" style="color: rgb(51,51,51);">some text</span></p><ul><li><span 
class="font-name-arial font-size-14" style="color: rgb(51,51,51);">[some text 
C]</span><li><span class="font-name-arial font-size-14" style="color: 
rgb(51,51,51);">[some text C]</span></ul>

What version of the product are you using? On what operating system?
1.5.3 Ubuntu Linux 13.10

Please provide any additional information below.
If there is any workaround/config that I could use, I appreciate you letting me 
know what I can do.

Tried 1.5.2, 1.5.1, and 1.5, so this was introduced in 1.5.

So I took some more time and tracked my issue down to 
fc50f4853af6f149ee839a3f629217eb837a410d
But I'm not sure how that is causing me to lose ending li tags. it seems to be 
dealing with tags that are required to be closed and my configuration, which 
was a copy of the tiny mce sample with some tweaks to allow empty tags, doesn't 
have this configuration.

Ok the following code seems to be the issue, Although I don't know why it was 
the way it was or why it changed to be the else condition rather than the if 
condition that always ran.

{{{

-       if (true) {
-           if (state.empty && isAllowedEmptyTag(rawName)) {
-               _printer.printText(" />");
-           } else {
-               // Must leave CData section first
-               if (state.inCData)
-                   _printer.printText("]]>");
-               // XHTML: element names are lower case, DOM will be different
-               _printer.printText("</");
-               _printer.printText(state.rawName.toLowerCase(Locale.ENGLISH));
-               _printer.printText('>');
-           }
-       } else {

-           // another element, so print a line break before that

-               if (_indenting && !state.preserveSpace && state.afterElement)
-                   _printer.breakLine();
