ArrayIndexOutOfBoundsException in GroovyParserVisitor.determineParenthesisLevel for Spock test

My potentially lying assistant tells me:

The test is using spock-core on the classpath. The issue is that when Spock is on the classpath, the Groovy compiler applies Spock's AST transformations automatically. This is a fundamental limitation - we can't parse Spock tests exactly as written when Spock is on the classpath because the transformations happen at compile time.
