After upgrading the Elastic JDK version in the spring boot application, stopped parsing the date type field to Java Date Objects.

The date field has a default format: strict\_date\_optional\_time||epoch\_millis

Java Code:

```auto
@Field(type = FieldType.Date, format = DateFormat.date_optional_time)
Date date1;

```

```auto
Sample.1: (Only Date)
date1: "2022-11-21"

```

When we fetch the data to this document it is giving below parsing error:

```auto
Method threw 'org.springframework.data.elasticsearch.core.convert.ConversionException' exception.
Unable to convert value '2022-11-21' to java.util.Date for property 'date1'

```

```auto
Sample.2: (Date and Time)
date1: "2022-11-21T07:27:28.000Z" 

```

This is getting parsed successfully. In the index, as we have the date format of optional\_date\_type it might have date only and date-time both. How can we parse such a date in Java Date Object in the latest version?

The same code was working in an older version.

Elastic Version - 7.17.1  
Spring Data Elastic: 7.17.4
