Date serialization and shading

Elastic Stack Elasticsearch

I am experiencing the same issue as this one.

I copied the code snippet provided by @baz and am able to run it without problems with mvn compile exec:java or from Eclipse but when building the uber jar with Maven shade I am getting

Exception in thread "main" java.lang.IllegalArgumentException: cannot write time value xcontent for unknown value of type class java.util.Date
at org.elasticsearch.common.xcontent.XContentBuilder.timeValue(XContentBuilder.java:751)
at org.elasticsearch.common.xcontent.XContentBuilder.timeField(XContentBuilder.java:719)
at Snippet.main(Snippet.java:21)

The shade plugin is configured as follows

    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-shade-plugin</artifactId>
    				<version>3.1.0</version>
    				<executions>
    					<execution>
    						<phase>package</phase>
    						<goals>
    							<goal>shade</goal>
    						</goals>
    						<configuration>
    							<createDependencyReducedPom>false</createDependencyReducedPom>
    							<transformers>
    								<transformer
    									implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />
    								<transformer
    									implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
    									<mainClass>org.apache.storm.flux.Flux</mainClass>
    									<manifestEntries>
    										<Change></Change>
    										<Build-Date></Build-Date>
    										<Implementation-Version>1.15.0</Implementation-Version>
    									</manifestEntries>
    								</transformer>
    							</transformers>
    						    <relocations>

    									<shadedPattern>hidden.org.apache.http</shadedPattern>
    								</relocation>
    								<relocation>
    									<pattern>org.apache.logging</pattern>
    									<shadedPattern>hidden.org.apache.logging</shadedPattern>
    								</relocation>
    								<relocation>

    									<pattern>org.apache.commons.logging</pattern>
    									<shadedPattern>hidden.org.apache.commons.logging</shadedPattern>
    								</relocation>
    							</relocations>
    						</configuration>
    					</execution>
    				</executions>
    			</plugin>
