As continue of investigating deadlock:

Thread #17 also displays strange stacktrace that normally should not happen:

• native(ObjC code) calls [myObject description];
• tries to marshal pointer(handle) to Java object in toObjCObject;
• it doesn’t find it in peer map and creates new Java instance/wrapper using ObjCObject.createInstance.

What is completely wrong here:

Due to a deadlock, a synchronization object in ObjC-related code became unavailable, causing the application to hang while trying to acquire a lock on it. It could also crash if the garbage collector (GC) was involved at that moment:

[ERROR] android.System: com.example.TestObject.finalize() timed out after 10 seconds
[ERROR] android.System: java.util.concurrent.TimeoutException: com.example.TestObject.finalize() timed out after 10 seconds

Few months since last Tracking slipped NPE and here we go again:

• same user reported;
• same scenario (code that handles a lot of NPE in try/catch);
• this time with Crashlytics.

Time for dissection…

There was a report in MobiVM matrix channel for crash that is happening only during running under debugger:

java.lang.NoClassDefFoundError: Could not initialize class com.sample.mobile.ios.network.RoboVmNetzwerkStatusController

issue#813 was reported as an issue with storekit2 bindings.

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘+[missing_RvmProduct_PurchaseOption appAccountToken:]: unrecognized selector sent to class 0x1332748a0’

With comments that simulator works but app fails on real device.
Lets investigate.

Tom-ski have reported production level crash caused by EXC_BAD_ACCESS by java code inside try/catch block. It is well known issue of code like this:

    public static void sayHello() {
        String s = null;
        try {
            s.toString();
        } catch (NullPointerException e) {
            e.printStackTrace();
        }
    }

caused by third party code that messes with SIGSEGV signal handler and makes it not accessible to RoboVM.

Breaking changes

AdMob is not longer a part of Firebase. It was moved out of Firebase package so its artifact id is changed:

• admob -> io.github.dkimitsa.robovm:robopods-google-mobile-ads-ios
• ump -> io.github.dkimitsa.robovm:robopods-google-ump-ios
• DynamicLinks removed as not available in Firebase anymore.

Silly typo fixed in CleverAds class package name: package org.robovm.pods.cleverads.* now.

Updated pods (ones with API changed)

• AppsFlyer v6.17.0 to v6.17.2
• CleverAds v4.1.0 to v4.1.2
• Google Mobile Ads v12.5.0 to v12.7.0
• Firebase v11.14.0 -> v12.0.0
