Dennis Gove commented on SOLR-9661:
-----------------------------------
I've thrown together a simple test that shows this exception.
{code}
@Test
public void replaceToExplanation() throws Exception{
StreamFactory factory = new StreamFactory().withFunctionName("replace",
ReplaceOperation.class);
StreamOperation operation = new ReplaceOperation("fieldA",
StreamExpressionParser.parse("replace(null, withValue=foo)"), factory);
StreamExpressionParameter expression = operation.toExpression(factory);
Explanation explanation = operation.toExplanation(factory);
}
{code}
Obviously, the toExplanation(...) line throws an exception but so does the
toExpression(...) line. I'm not sure why this hasn't come up before as
toExpression is used extensively, particularly by the parallel stream.
