Using JDK 11 causes NoClassDefFoundError

[acet]

On the same code base using JDK 8 works as expected, but after switching to JDK 11 a NoClassDefFoundError is thrown

Caused by: java.lang.NoClassDefFoundError: javax/activation/MimeType
	at org.zalando.logbook.servlet.RemoteRequest.isFormRequest(RemoteRequest.java:119)
	at org.zalando.logbook.servlet.RemoteRequest.withBody(RemoteRequest.java:100)

using both JDK 8 and JDK 11

Possible Fix

Include

        <dependency>
            <groupId>com.sun.activation</groupId>
            <artifactId>javax.activation</artifactId>
            <version>1.2.0</version>
        </dependency>

as a dependency in logback-servlet

Context

I use JDK 11 and so I must currently include javax.activation in my dependencies currently to work around this
