> Key: DAFFODIL-2628
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2628
> Project: Daffodil
> Issue Type: Bug
> Components: Back End, Middle "End"
> Affects Versions: 3.2.1
> Reporter: Mike Beckerle
> Assignee: Mike McGann
> Priority: Major
> Fix For: 3.5.0
>
>
> Debugging a schema I created this little thing to print out a length I wanted
> to see:
> ```
> <dfdl:assert test='{ dfdlx:trace(dfdl:valueLength(message,
> "bytes"),"contentLen") }'/>
>
> ```
> Notice the mistake. I forgot to compare the value to 0 in the test.
> That expression returns an integer.
> If you fix the expression (add " ge 0") then everything works fine.
> But with the mistake you get an abort at runtime:
> ```
> trace contentLen:DataValue(true)
> org.apache.daffodil.exceptions.Abort: Invariant broken. Runtime.scala -
> Leaked exception: java.lang.ClassCastException: class java.lang.Boolean
> cannot be cast to class java.lang.Long (java.lang.Boolean and java.lang.Long
> are in module java.base of loader 'bootstrap')
> java.lang.ClassCastException: class java.lang.Boolean cannot be cast to class
> java.lang.Long (java.lang.Boolean and java.lang.Long are in module java.base
> of loader 'bootstrap')
