> When loading transaction metadata from a transaction log partition, if the

> logic at
> [https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/coordinator/transaction/TransactionStateManager.scala#L482]
> will be skipped. Since "currOffset" is not advanced to next offset of last
> batch properly, TransactionStateManager.loadTransactionMetadata method will
> be stuck in the "while" loop at
> [https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/coordinator/transaction/TransactionStateManager.scala#L438.|https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/coordinator/transaction/TransactionStateManager.scala#L438,]
