Error with versions of JDK while creating report using PhpJasper

Question

I trying to create some code with PHPJasper, but at same line I get error. I think it's problems with Java SE versions.

File hello_world.jasper is already exist in my project.

Source code:

require __DIR__ . '/vendor/autoload.php';

use PHPJasper\PHPJasper;

$jasper = new PHPJasper;

$input = __DIR__ . '/vendor/geekcom/phpjasper/examples/hello_world.jasper';
$output = __DIR__ . '/vendor/geekcom/phpjasper/examples';
$options = [
    'format' => ['pdf', 'rtf']
];

$jasper->process(
    $input,
    $output,
    $options
)->execute();

var_dump($jasper);

Error in console for line with execute():

Exception in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')

Java version:

java -version
openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Ubuntu-1ubuntu219.04)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu219.04, mixed mode, sharing)

How can I fix it?

Yeah I would try with version <=8 it's trying to cast as URLClassLoader which works in version 8 or less. — Petter Friberg, Aug 19 '19 at 13:50

I have a solution of this problem.

I remove all java packages (sudo apt-get remove openjdk...) and install again with version Java JDK 1.8 (instruction for ubuntu)

After this I got correct version of Java:

java -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

And I don't have errors in my project
