Not easily. However, I've managed to solve this issue by setting the
current thread context class loader with the expected one.
final old = Thread.currentThread().getContextClassLoader()
try {
final loader = IgnitePlugin.class.getClassLoader()
Thread.currentThread().setContextClassLoader(loader)
Ignition.start( config() )
}
finally {
Thread.currentThread().setContextClassLoader(old)
}
