IndexOutOfBoundsException in Parser.parse()

[squarejesse]

I was using jsoup 1.21.1 to crawl some webpages and it crashed.

java.lang.IndexOutOfBoundsException: Index -1 out of bounds for length 0
	at java.base/jdk.internal.util.Preconditions.outOfBounds(Preconditions.java:100)
	at java.base/jdk.internal.util.Preconditions.outOfBoundsCheckIndex(Preconditions.java:106)

	at org.jsoup.parser.TreeBuilder.parse(TreeBuilder.java:76)
	at org.jsoup.parser.Parser.parse(Parser.java:238)

Here’s the code that triggered the crash.

String s; = // see attached page.html.
String url = "https://energyinnovation.org/report/updated-economic-impacts-of-u-s-senate-passed-one-big-beautiful-bill-act-energy-provisions/"
Document document = Jsoup.parse(s, url);

Thanks for an awesome library.

Hi Jesse,
