lhotari opened a new pull request #14617:
URL: https://github.com/apache/pulsar/pull/14617
### Motivation & Modifications
- refactor code in ManagedCursorImpl to get rid of 4 FastThreadLocal
variables
- it is hard to understand the code and it's not optimal
since it will do object allocations for Long instances stored in the
FastThreadLocal
variables.
- there's less overhead in having a simple private class to hold the
fields required for the state
- ordinary local variables cannot be used since .forEach accepts a lambda
and local variables cannot be mutated in a lambda
