Dears,
We are going to upgrade Elasticsearch 5.2.2 using JDK 1.8.0\_121 ([https://www.elastic.co/guide/en/elasticsearch/reference/5.2/\_installation.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/_installation.html)) to ES 5.3.2.
The strange thing is that for both 5.3 and 5.4 it is stated that 1.8.0\_73 is recommended (see
[https://www.elastic.co/guide/en/elasticsearch/reference/5.3/\_installation.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/_installation.html))
Could you please confirm if is it recommended to downgrade JDK version or it is just a typo in the installation manual for 5.3/5.4 versions?
Regards
Ewa
