Hi, I'm trying to follow tutorial but I'm getting such exception

java.lang.VerifyError: class org.zkoss.zats.mimic.impl.emulator.EmulatorBuilder$WebWebInfResource overrides final method release.()V at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at org.zkoss.zats.mimic.DefaultZatsEnvironment.init(DefaultZatsEnvironment.java:82) at org.zkoss.zats.mimic.Zats.init(Zats.java:46)

Can anyone help me with this? Any suggestions are welcome because there are no reference how to solve this problem in google. Here are dependency that I use

compile group: 'org.zkoss.zk', name: 'zkbind', version: '7.0.1'
compile group: 'org.zkoss.zk', name: 'zul', version: '7.0.1'
compile group: 'org.zkoss.zk', name: 'zkplus', version: '7.0.1'
compile group: 'org.zkoss.zk', name: 'zhtml', version: '7.0.1'
testCompile group: 'junit', name: 'junit', version: '4.11'
testCompile group: 'org.zkoss.zats', name: 'zats-mimic-ext7', version: '1.2.0'

UPD: I find out that this problem associated with Jetty version that I use, it's 9.1.3 but ZATS is depends on 7.6 So, now is the question - how can I update Jetty version for ZATS ?

I'm getting the same problem, my code relies on servlet-api 3.0 and I need Jetty 9 for testing, but ZATS can't startup with Jetty 9, so I can't unit test my code :-(
