&Do you have sufficient free space on your hard drive?
Maybe your disk is full.
No, Disk Space is enough approx. ~ 96 GB
&Did it happen once only, or this is a repeating error?
No it occurs multiple times.

For more reference there is some logs from Catalina.out after tomcat startup.
Jul 17, :33 AM org.piler.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.

Dear Christopher,
The solution is fine, but first thing we need to identify the root cause.
If it is the problem of "loading a JSP-based class file." Why it is happened in production environment?
Any solid reason ?

Who knows?
It is your environment and your file.
It is up to you to
perform the diagnostics.
(Or hire some 3rd party and to provide them access to your system).
For starters, we do not know what file is broken.
Also you stacktrace does not show the "root cause". Where this class
loading error was detected?
There shall be stacktrace from
java.lang.ClassFormatError that was wrapped by ServletException.
only provided 3 lines of stacktrace of ServletException.
It may be compiler's fault -- current version is 7.0.63 and it has a
newer version of compiler,
or you are hitting some size limit -- quotas, disk partition size, 2Gb
limit, etc.,
or you have broken file / faulty HDD --
Maybe not the class file for a JSP page is broken, but some other
class file on your system....

Clean your maven repository:
(By default in your user folder)
~/.m2/repository
Then perform a clean install so it download the dependencies again and recompile your entire project:
mvn clean install
13.5k53664
ClassFormatError: Truncated class file
means that one of the class file is corrupted. Try to run clean goal to do the bad classes cleanup before you run the install target. Or simply combine both the targets and do mvn clean install for your project.
42.4k63569
I can see from your stac-trace that you are using reflection. Is the class working when you use it normally? Is it possible that when you use reflection, the class is unreachable or mis-used?
14.1k113984
After all the research and changing things, i found the solution,
I updated Maven dependency,it doesn't work,
I uninstall tomcat and Java and then reinstall it.
And the error is that Java Jdk is corrupted due to some reason i Dont Know it why.....
and thanks all for your suggestions
