What was the reason of "access denied" exception while executing Runtime.exec() on Android?

Question

I have native executables compiled for Android and they are located in /data/data/my.app.package so I believe app is able to execute executables there.

Unfortunately Runtime.exec() causes an "access denied" exception. How can I know what object (path, file, etc) executable was trying to get access to? App reads files in /data/data/my.app.package and write files there.

No debug messages are in the log, the device is rooted.

The problem was that unzipping using Java Zip API does not save flags so files were not marked as executables. used chmod 0755 (file) to fix it
