Apache Tomcat 7.0.62 发布，此版本包括一系列 Bug 修复及性能改善： 57772: When reloading a web application and a directory representing an expanded WAR needs to be deleted, delete the directory after the web application has been stopped rather than before to avoid potential ClassNotFoundExceptions. (markt) 57801: Improve the error message in the start script in case the PID read from the PID file is already owned by a process. (rjung) 57824: Correct a regression in the fix for 57252 that broke request listeners for non-async requests that triggered an error that was handled by the ErrorReportingValve. (markt/violetagg) 57841: Improve error logging during web application start. (markt) 57856: Ensure that any scheme/port changes implemented by the RemoteIpFilter also affect HttpServletResponse.sendRedirect(). (markt) 57896: Support defensive copying of "cookie" header so that unescaping double quotes in a cookie value does not corrupt original value of "cookie" header. This is an opt-in feature, enabled by org.apache.tomcat.util.http.ServerCookie.PRESERVE_COOKIE_HEADER system property.
