Hi,
 
We are encountering a recurring crash in our production app, and the stack
trace shows it is occurring inside the Trichrome WebView (Chromium).
 
*Fatal Exception:*
Caused by java.lang.IllegalArgumentException: fromIndex(0) > toIndex(-1) at
java.util.Arrays.rangeCheck(Arrays.java:727) at
java.util.Arrays.binarySearch(Arrays.java:2268) at

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1103)
 
*Observations*
 
-

The crash appears to be caused by an invalid index range being passed to
Arrays.binarySearch inside WebView internal code.
-

This is happening entirely inside SDK/Chromium code and not triggered
directly by our app logic.

*Impact*
We are also observing that the number of occurrences is increasing day by
day, which is raising significant concern.
 
Thanks & Regards,
Kajal
