Example from my downloaded zip file:

Code:

$ unzip -l  apache-tomcat-11.0.0-M19.zip | grep index.jsp | grep ROOT
    12458  09 04 24 12:06   apache-tomcat-11.0.0-M19/webapps/ROOT/index.jsp
$ pwd
/home/murugesandins/apache-tomcat-11.0.0-M19/webapps/ROOT
$ fl index.jsp | egrep -v "^$";echo $?
1
$# Initially https://127.0.0.1/ was reporting => HTTP Status 404 – Not Found
$ ls | grep -i index.jsp
-rwxrwx---+ 1 murugesan openssl 12458 May  5 04:13 index.jsp.Original
-rwxrwx---+ 1 murugesan openssl 12478 May  8 15:54 index.jsp.backup01
$ type cp
cp is aliased to `/usr/bin/cp -i '
$ cp index.jsp.backup01 index.jsp
$# after this https://127.0.0.1 reporting valid content of => Apache Tomcat/11.0.0-M19

Validate your index.jsp file locations/permissions/... at your tomcat webapps directory
including contents of index.jsp (if you have modified)

HTTP Status 500 – Internal Server Error
Type Exception Report
Message org.apache.jasper.JasperException: java.lang.ClassNotFoundException: org.apache.jsp.index_jsp

java.lang.ClassNotFoundException exception happens when related .class file not found by java or related CLASSPATH not having required jar file/related directory environment variable.
shutdown tomcat
if you have done make clean(development oriented) perform make again and execute related script(Example: . ~/.bashrc) to set required environment variables again.
After that start tomcat
We can have these steps at automated script(always) if required before starting tomcat.

Not sure, sometimes it seems to work and sometimes not.

Let me describe a sample action by the client using internet banking:
1. login => (Eg: access index.jsp)
2. create a session id at client coockies and always validate the cookie timeout periods.
3. Intermediately assume that client is donating 100.00 INR to prime minister to get a refund for last 10 months using that current session id.
4. Developer of that page invoking a page which is dependent on NRF.jar file which is not set at CLASSPATH environment variable.
Due to this 500 error reported at client side.
5. Developer handled to remove/reset the cookie at client and server side asking the client to re-login again.
I feel that the same condition applicable to your working/non-working exceptions at tomcat.
Hence I have informed to include related CLASSPATH and all tomcat environment variables at start_tomcat.sh (set all, and then call startup.sh if tomcat not at execution mode inside current host including that port number not in use by any other apps)

Following comment not related to this query.
However I am sharing some automated script at localhost whenever I login at 127.0.0.1:
a) Start bash.exe to check battery percentage and if it is greater than 98% open notepad.exe and provide alert to switch off battery
b) start putty.exe at 127.0.0.1 if not at execution mode now.
c) start firefox.exe if not at execution mode now.
d) exit from this automated script
e) execute above automated script using startup.cpp C:\Users\%USERNAME%\AppData\Roaming\Microsoft\Windows\STARTM~1\Programs\Startup\startup.exe
Hence I have informed perform automated script to invoke startup.sh after setting all requirements for tomcat/any servers.
you can understand => ALL requirements...using lsof /-d /-f /ps/.../sudo required commands using automation at any OS.
