Native crash on an Android-Java based app?

问题

Background

My app has 100% code written in Java, it doesn't need to make any heavy operations.

The app itself uses only the next libraries, yet non of them have JNI code:

ActionBarSherlock
google-play-services_lib

The problem

Today I got a weird crash report, which doesn't show any normal exception information .

The report was sent via a "Galaxy S5 (klte)" device, with Android 4.4 .

Here's the crash report title:

Native crash at /dev/ashmem/dalvik-jit-code-cache in
/dev/ashmem/dalvik-jit-code-cache (deleted)

And here is the crash content :

*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***

#01 pc 00026a55 /dev/ashmem/dalvik-jit-code-cache (deleted)

code around pc: SOME_NUMBERS

code around lr: SOME_NUMBERS

where "SOME_NUMBERS" look like a lot of random hexadecimal numbers.

What I've tried

Some websites claim people should decode images in a synchronized manner (yet I have made many apps that do it and never got this error).

The thing is, for this app I already decode the bitmaps using a single thread, so this can't be it.

I didn't find any other thing that can be related to things I do on the app, that have anything to do with native handling of code.

I thought, maybe since it's Android 4.4, the user moved to "ART" runtime, but the crash report has the word "dalvik" in it, so that's probably not it (and even if it was this, I have no idea how to handle it).

To make things even more unclear, the user wrote "Not sure" in the report... :(
