> Starting from 1.10.0 `PropertyValue::isExpressionLanguagePresent` seems to always return true on non-null values. 
> Query parser treats property value as a string literal expression, adds it to expression list on a query object, and, since expressions list is not empty, the property is considered as having expression language.
> Seems to be introduced  by this commit https://github.com/apache/nifi/commit/4f50f30ad7329540a707be835c23acee86d4cfb4#diff-7baf1e313bdccf02cbc790319fd86ebb1a4a5f8a283bcae86f0510e4264548e3
