Hi,  
I am trying to upgrade spring data Elasticsearch from 4.1.10 to 4.2.2

I have a date field definition like below

> **@Field(type = FieldType.Date, format = DateFormat.date\_optional\_time, index = false)**  
> private LocalDate executionDate

It works with spring data Elasticsearch 4.1.10 but fails in 4.2.x (4.2.0, 4.2.1, 4.2.2).  
Getting the below error in bean creation of repository.

> Caused by: java.lang.NullPointerException: Cannot invoke "java.lang.Class.isEnum()" because "componentType" is null

Have tried many formats.  
**Using the keyword "format" or "pattern" inside @Field throws this error.**  
Any suggestion would greatly help .

Thanks in advance.

Thanks for the quick response Alexander.  
The issue was due to a conflict in my ES version.

I have fixed the same.
