art/runtime/stack.cc:205] Check failed: success Failed to read the this object in void ....handleLoadPackage(de.robv.android.xposed.callbacks.XC_LoadPackage$LoadPackageParam)

[3c71]

I built an Xposed module since a few years, and users are now reporting a weird issue in which the app itself no longer starts when its integrated module is enabled.

When module is enabled, the Xposed logs shows many lines like this:

art/runtime/stack.cc:205] Check failed: success Failed to read the this object in void ccc71.at.xposed.at_xposed_enabled.handleLoadPackage(de.robv.android.xposed.callbacks.XC_LoadPackage$LoadPackageParam)

Not sure what it means or if it relates to the app no longer starting, but it's odd enough as the method in question is quite simple:

@Override
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable
{
	String self = at_xposed_helpers.getPackageName();

	if (lpparam.packageName.equals(self))
	{
		findAndHookMethod("ccc71.at.xposed.at_xposed_helpers", lpparam.classLoader, "isXposedEnabled", new XC_MethodHook()
		{
			@Override
			protected void beforeHookedMethod(MethodHookParam param) throws Throwable
			{
				param.setResult(at_xposed_helpers.VERSION);
			}
		});
	}
}

static String getPackageName()
{
    return BuildConfig.XPOSED_PACKAGE;
}

Can anybody help me understand how an Xposed module being enabled would prevent the hosting app from starting? There's nothing in logcat, no ANR nor any tombstones when this happens. Just those lines in the log attached.

This is probably one of the issues mentioned here: #72
Please see my latest reply in that issue.

@rovo89 you mean here rovo89/Xposed#275

[rovo89]

These crashes should be fixed with v89 which I released last night.

I'm still seeing this issue with v89.

C3 Toolbox is not running after boot and doesn't start when selected in the launcher.

Xposed log is full of:

Sorry to hear that. I’m running v89 on top of Magisk and have no issues so far. Are you sure v89 is loaded? Have you tried the ‘fix’ referred in rovio threads: cmd package compile --reset ccc71.at Many users have reported it fixes the issue, however it might only be temporary? It might be permanent if the issue comes from ‘old’ cache still providing old code somehow. 3C.

I'm very sure I'm running v89 correctly.

It's fine right after I boot to system from recovery after wiping dalvik/art cache and cache, but it starts/keeps failing again after some time.

I'm pretty sure it's directly related to the issues caused by BackgroundDexOptService described in rovo89/Xposed#275

[rovo89]

Then I'll have to look at these issues again next year. For now, my focus is on Oreo, especially as the latest fixes seem to work for most people.

I'd just like to mention again that the background dexing and resetting the compiled code is just about the symptoms. Please don't call this a fix.
