------------------------------------
Assignee: Josh Adams
> expresion on all unsignedInt element and variables results in cast exception
> ----------------------------------------------------------------------------
>
> Key: DAFFODIL-2327
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2327
> Project: Daffodil
> Issue Type: Bug
> Components: Back End
> Affects Versions: 2.6.0
> Reporter: Mike Beckerle
> Assignee: Josh Adams
> Priority: Major
> Fix For: 3.0.0
>
>
> I have a schema with an expression. The expression uses the value of an
> element of type unsignedInt, and some variables also all of type unsignedInt.
> The rest of the expression is just add and multiply and subtract.
> I get this exception:
> {code:java}
> org.apache.daffodil.exceptions.Abort: Invariant broken. Runtime.scala -
> Leaked exception: java.lang.ClassCastException: java.math.BigInteger cannot
> be cast to java.lang.Long
> java.lang.ClassCastException: java.math.BigInteger cannot be cast to
> java.lang.Long
> at
> org.apache.daffodil.infoset.DataValue$.getLong$extension(DataValue.scala:88)

> org.apache.daffodil.dpath.UnsignedIntToLong$.computeValue(ConverterOps3.scala:91)

> {code}
> There is a conversion UnsignedIntToLong being invoked. This just calls a
> getLong which just calls a v.asInstanceOf[JLong] cast, which fails because v
> is a java BigInteger.
