Failed to initialize FeatureHub client - Java Spring boot

[chkp-talash]

Hi,
I am using the java-client-sse package version 1.4 in my Java Spring boot project (Java 8) and I am getting an error while running init() on EdgeFeatureHubConfig instance.
I am suspecting it related to the fact that I have another package in my project that uses okhttp3 with version 3.8.1.
Does it mean that I cannot use this sdk? is there any solution except for using restApi?

The error:

Heya! Thanks for asking - okhttp4 is supposed to be binary compatible with okhttp3, so I would recommend trying to upgrade to 4.x and trying it out. https://square.github.io/okhttp/changelogs/upgrading_to_okhttp_4/
