GRAVE: One or more Filters failed to start. Full details will be found in the appropriate container log file

GRAVE: Context [/JSP] startup failed due to previous errors
dez 16, 2018 8:56:28 PM org.apache.catalina.loader.WebappClassLoaderBase clearReferencesJdbc
ADVERTÊNCIA: The web application [JSP] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
dez 16, 2018 8:56:28 PM org.apache.catalina.loader.WebappClassLoaderBase clearReferencesThreads
ADVERTÊNCIA: The web application [JSP] appears to have started a thread named [Abandoned connection cleanup thread] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:
java.lang.Object.wait(Native Method)

INFORMAÇÕES: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
