SVG TextPath causes StringIndexOutOfBoundsException
Hello,
We are trying to render a SVG with a textPath element in a PDF, but we keep getting the following error: java.lang.StringIndexOutOfBoundsException: String index out of range: 0
Note: The problem is caused by the SVG file, so I am not 100% sure it should be an issue here or on batik. Any other tested SVG works, the issue only comes up when using the textPath-element.
Note 2: We develop in Kotlin, but we do not believe the issue is caused by that.
We tried textPath without attributes and/or different attributes. We tried to move the referring path-element to the parent, but all to no avail.
Fix or workaround would be appreciated.
