This may happen if you have JSoup version greater than 1.6.3 like:

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.15.2</version>
</dependency>

Replace it with version 1.6.3:

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.6.3</version>
</dependency>

TeaVM version 0.7.0 at the moment does not play well with JSoup versions greater than 1.6.3 yet.
