Leak in Runnable

[tito]

I was using periodically a method decorated with @run_on_ui_thread, and i just got a fail:

E/dalvikvm(16389): JNI ERROR (app bug): local reference table overflow (max=512)
W/dalvikvm(16389): JNI local reference table (0x67b47d30) dump:

I/dalvikvm(16389): "Thread-11527" prio=5 tid=11 RUNNABLE

So i guess we're leaking Runnable here.

Bad for things like Toast that might create that many runnables and must be
done on UI thread. Is there any API to clean this up at the right time?

Actually, Runnable is part of the android extension, not pyjnius. Somebody already opened the issue in python-for-android, let's continue the discussion in that issue.
