SP1 spagoBi error : At least one JAR was scanned for TLDs yet contained no TLDs

After spago Bi server startup i have faced the error and i look into the log files and error as below:

Apr 27, 2015 4:42:05 PM org.apache.jasper.compiler.TldLocationsCache tldScanJar
INFO: 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.

to remove this error we need to modify the "logging.properties" file. which is reside at
apache tomcat * > conf > logging.properties.

and need to uncomment the line

# To see debug messages in TldLocationsCache, uncomment the following line:
org.apache.jasper.compiler.TldLocationsCache.level = FINE


Start the server and check for error:

if still error is coming continuously then follow below steps:
- stop SpagoBIServer
- move to folder apache tomcat\webapps\SpagoBI\WEB-INF\lib
- make a backup copy of the file hibernate3.6.2.jar
- with a zip navigator (for example 7zip/peazip) navigate the jar file hibernate3.6.2.jar
- open the folder hibernate3.6.2.jar\org\hibernate\mapping\
- delete the classes: Table.class and Table$ForeignKeyKey.class
- Start the server
