By the way, I ran into this exact issue in a Liferay 7.2 instance on Java 11. <br>I had this configuration in the build plugin of my service pom.xml:<pre><code>&nbsp;&nbsp; &nbsp;<build>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugins>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<groupid>org.apache.maven.plugins</groupid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<artifactid>maven-compiler-plugin</artifactid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<version>3.8.1</version>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<source>1.8
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<target>11</target>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;...
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugins>
&nbsp;&nbsp; &nbsp;<build></build></build></code></pre>This was throwing the error because the Java runtime version of my artifact was set to 11...but Jodd only works when targeted for Java 8 maximum. What I did, is changed the configuration to the following:<pre><code>&nbsp;&nbsp; &nbsp;<build>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugins>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<groupid>org.apache.maven.plugins</groupid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<artifactid>maven-compiler-plugin</artifactid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<version>3.8.1</version>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<source>1.8
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<target>1.8</target>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;...
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugins>
&nbsp;&nbsp; &nbsp;<build></build></build></code></pre>After building and deploying the error was gone.</body></html>Enrique Valdes Lacasa2020-05-28T17:42:37ZRE: Error while deploying portlet with remote serviceOlaf Kockhttps://uat.liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=1186778592020-03-06T10:47:43Z2020-03-06T10:47:43Z<div class="quote-title">Dhruv Pandey:</div><blockquote><br />Took 2 days to figure this out.
