> Issue Type: Bug

> JoltTransformJSON allows for multi-line Java comment anywhere in the Jolt
> spec except for the leading line when the Jolt Spec is specified as text (not
> with a file path). The error message is not really helpful as to what the
> issue is, as seen with the following error message
> {code:java}
> 'Jolt Specification' is invalid because Specification not valid for the
> selected transformation: Read JOLT Transform failed{code}
> but ultimately the cause of the error is a java.io.FileNotFoundException.
> On the other hand, ValidateJson does not allow for any type of comments, as
> the com.fasterxml.jackson.databind.ObjectMapper it uses for creating Json
> schemas object uses strict parsing and does not allow for Java comments.
> There should be a com.fasterxml.jackson.core.JsonParseException thrown if a
> comment is used before the actual schema
> {code:java}
> // Single line Java comment
> {
> "$schema": "https://json-schema.org";,
> "type": "object",
> "additionalProperties": true
> }
> /*
> Multi-line Java comment
> */
> {
>
> "$schema": "https://json-schema.org";,
> "type": "object",
> "additionalProperties": true
> } {code}
> or inside the schema
> {code:java}
> {
> // Single line Java comment
> "$schema": "https://json-schema.org";,
> "type": "object",
> "additionalProperties": true
> }
> {
> // Multi-line Java comment
> "$schema": "https://json-schema.org";,
> "type": "object",
> "additionalProperties": true
> } {code}
> yet when there is leading multi-line Java comment the error thrown is
> java.io.FileNotFoundException.
