[GitHub] [pulsar] Shoothzj opened a new issue #12159: NPE When create OpReadEntry
Shoothzj opened a new issue #12159:
URL: https://github.com/apache/pulsar/issues/12159
**Describe the bug**
NPE When `OpReadEntry.create()`. When the `ledgerId` in `ManagedLedgerImpl.ledgers` is null.
the call to `OpReadEntry.create()` will trigger `readEntryFailed` callback but this time the cursor of `OpReadEntry` is still unseted.
More seriously, it will make the variable `havePendingRead` can't become true again.
**To Reproduce**
It's quitely hard to reporduce the problem. In our environment, we shutdown all bookkeepers meanwhile, has the probability to reporduce it.

Thanks, that's same as #11282/#11796. I should search more carefulness before I submit the issue. Thank you very much.

IMHO, it probably need a sync callback failure instead of async callback failure.
Any better idea to fix this problem ? Thanks for your help.
