According to the stack trace:
java.lang.NoClassDefFoundError: org/apache/commons/lang/ObjectUtils
at lingo3g.s.hashCode(Unknown Source)
It looks like lingo3g - lingo3g isn't on Maven central and looks like it
requires a license to download. You would have to contact them to see if it
still uses commons-lang. You could also copy in commons-lang dependency.
