The reason is that the response object in this case is not set at [this
point](https://github.com/apache/incubator-geode/blob/develop/gemfire-core/src/main/java/com/gemstone/gemfire/internal/cache/tier/sockets/command/CommitCommand.java#L122
):
A sequence that leads to the error is following:
<JTA Transaction Manager>.begin()
region.put()
<JTA Transaction Manager>.registerSynchronization(TXStateProxyImpl)
<JTA Transaction Manager>.rollback()
TXStateProxyImpl.beforeCompletion()
TXStateProxyImpl.afterCompletion()
Im my scenario the transaction looks to roll back successfully even after NPE
is thrown. Still some parts of the relevant code might be missed in that case
and could lead potentially to other problems (e.g. [leaving hosted TX state
behind](https://github.com/apache/incubator-geode/blob/develop/gemfire-core/src/main/java/com/gemstone/gemfire/internal/cache/tier/sockets/command/TXSynchronizationCommand.java#L153))

> The reason is that the response object in this case is not set at [this
> point](https://github.com/apache/incubator-geode/blob/develop/gemfire-core/src/main/java/com/gemstone/gemfire/internal/cache/tier/sockets/command/CommitCommand.java#L122
> ):
> A sequence that leads to the error is following:
> <JTA Transaction Manager>.begin()
> region.put()
> <JTA Transaction Manager>.registerSynchronization(TXStateProxyImpl)
> <JTA Transaction Manager>.rollback()
> TXStateProxyImpl.beforeCompletion()
> TXStateProxyImpl.afterCompletion()
> Im my scenario the transaction looks to roll back successfully even after NPE
> is thrown. Still some parts of the relevant code might be missed in that case
> and could lead potentially to other problems (e.g. [leaving hosted TX state
> behind](https://github.com/apache/incubator-geode/blob/develop/gemfire-core/src/main/java/com/gemstone/gemfire/internal/cache/tier/sockets/command/TXSynchronizationCommand.java#L153))
