javax.swing.text.html.parser.Parser parseScript ignores a character after comment end

FULL PRODUCT VERSION :
# java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)

A DESCRIPTION OF THE PROBLEM :
When html that containes script fileld like below is parsed, eof.script error is throwen.
     <script type="text/javascript"><!--
             function a(a) {}
     //--></script>

It works fine when written as below:
     //--><SPACE></script>

     //--><CR>
     </script>

It seems that because first character after END_COMMENT("-->") is ignored,
so parseScript() can't find SCRIPT_END_TAG("</script>").

It looks like a side effect of JDK-8078268 fix introduced in 8u112.
When run in 8u111, either pattern works fine.

REGRESSION. Last worked in version 8u111
