Using JDK 11 getting NoClassDefFoundError

[supadhay]

For JDK 11 I am getting ClassDefNotFoundError for Sink class which is part of logbook-api jar whereas for JDK 8 it is working perfectly.

Description

My code:
OkHttpClient.Builder okBuilder =
new OkHttpClient.Builder()
.readTimeout(Duration.ofSeconds(120))
.writeTimeout(Duration.ofSeconds(120))
.addNetworkInterceptor(
new LogbookInterceptor(
Logbook.builder()
.headerFilter(authorization())
.queryFilter(accessToken())
.bodyFilter(bodyFilter)
.sink(
new DefaultSink(new JsonHttpLogFormatter(), new DefaultHttpLogWriter()))
.build()));

Here is the error log

I haven't used Java 11 yet. Does it have to do with modules?

Even I have started using jdk 11 recently. If you have any clue on if I missed any module of jdk 11.
I have look for it if I find any blogs.

There were jar conflicts for logbook-api, Now I am able to solve it. Thanks
