Summary: 0002108: PHPMyAdmin fails with NullPointerException
Description: Tested phpMyAdmin 2.11.1.2 and found a NullPointerException caused
by a null Env ref in the thread local Env table. This issue was
reported on the quercus forum with the following trace:

500 Servlet Exception
java.lang.NullPointerException
at com.caucho.quercus.env.Value.toStringValue(Value.java:700)
at _quercus._libraries._js_0escape__lib__php$fun_PMA_escapeJsString.call(D:/resin-pro-3.1.3/webapps/phpmyadmin/libraries/js_escape.lib.php:65)
at com.caucho.quercus.program.CompiledFunction.callRef(CompiledFunction.java:56)
at _quercus._index__php.execute(D:/resin-pro-3.1.3/webapps/phpmyadmin/index.php:127)
at com.caucho.quercus.page.QuercusPage.executeTop(QuercusPage.java:119)
at com.caucho.quercus.servlet.ResinQuercusServlet.service(ResinQuercusServlet.java:146)
at com.caucho.quercus.servlet.QuercusServlet.service(QuercusServlet.java:353)
Steps To Reproduce:
Additional Information: This problem seems to be the result of a missing call to Env.start(),
so the thread local Env ref never gets initialized.

After further review, the problem actually seems to be a result
of a call to session_write_close near the top of index.php. This
case seems to already be covered by the following QA test.

php/1k6l.qa
