Zookeeper : java.lang.ClassNotFoundException: org.apache.zookeeper.admin.ZooKeeperAdmin after updating spring boot

Question

I am trying to update an springboot application which uses org.apache.zookeeper.zookeeper. After updating the spring boot version. I am getting one of the two errors given below depending upon the version used.

Error 1 - (For new version provided below)

or

Error 2 - (For some other versions of zookeeper and curator provided in thread 1 provided below)

Caused by: java.lang.ClassNotFoundException: org.apache.zookeeper.admin.ZooKeeperAdmin

Old versions: (Working good)
Java - 8
SpringBoot - 2.3.3.RELEASE
Zookeeper - 3.4.12
Curator - 4.0.1

New version: (Spring managed versions)
Java - 8
SpringBoot - 2.7.4
Zookeeper - 3.6.0
Curator - 5.1.0

Many threads mentions that the issue is because of incompatible zookeeper and curator versions.

There are some threads already available regarding the issue

• Zookeeper : java.lang.ClassNotFoundException: org.apache.zookeeper.admin.ZooKeeperAdmin
  I tried every solution provided in the this thread and also some other combinations but none seems to work. I tried to use the old version and updating the rest. This too didn't work.
• Apache Curator Unimplemented Errors When Trying to Create zNodes
  I am not accessing the curator directly as provided in this thread and I believe the zookeeper internally uses curator.

Is there any other dependency I need to upgrade? or Do I need to upgrade the java? Please mention if you need some more info.
