Completion () expires after 30 seconds

Question

I see several failures in the fabric that look like this:

Fatal Exception: java.util.concurrent.TimeoutException: android.text.TextPaint.finalize() timed out after 30 seconds
       at android.graphics.Paint.finalizer(Paint.java)
       at android.graphics.Paint.finalize(Paint.java:2437)
       at java.lang.Daemons$FinalizerDaemon.doFinalize(Daemons.java:202)
       at java.lang.Daemons$FinalizerDaemon.run(Daemons.java:185)
       at java.lang.Thread.run(Thread.java:833)

Fatal Exception: java.util.concurrent.TimeoutException: java.io.FileInputStream.finalize() timed out after 10 seconds
       at java.io.FileDescriptor.valid(FileDescriptor.java:87)
       at libcore.io.IoUtils.close(IoUtils.java:37)
       at java.io.FileInputStream.close(FileInputStream.java:121)
       at java.io.FileInputStream.finalize(FileInputStream.java:142)
       at java.lang.Daemons$FinalizerDaemon.doFinalize(Daemons.java:187)
       at java.lang.Daemons$FinalizerDaemon.run(Daemons.java:170)
       at java.lang.Thread.run(Thread.java:856)

I am not sure why and what code of my Android application causes these failures, I also cannot replicate it. Maybe one of you had a similar problem and solved it?
