_log is null? It's final, can't happen.

Looks like the kind of error we used to see a lot on the RPi with the old JVM. First time we've seen something like it on the 1.8.0-ea JVM.

Is there a newer JVM version available? Time to update if so.

Hmm, unless the recent zab changes are causing it (VerifiedEstablishState?) - CC'ing zab

comment:4 Changed 6 years ago by Zlatin Balevsky

I don't see how it's possible, but just to be safe I'm overriding the method with a noop in revision 99e4bd9ecf8f253fbc7ab6fcaddfeb28dd97e168

Replying to zzz:

Latest is jdk-8-ea-b100-linux-arm-vfp-hflt-24_jul_2013.tar.gz

comment:6 Changed 6 years ago by tyro

Rocking 0.9.7-12. Need to upgrade JVM + I2P to latest versions.
A crit appeared in the below logs hence my update.
