Re: [ljc] JVM is messed up when system clock is rolled backward

Hi,

I guarantee we do not have sleep() to synchronize things :), we are using java.concurrency primitives. The most problematic thing is the ScheduledExecutor: it just stops. The backup plan would be 1) patch the JVM or 2) rewrite in native some of those function but I am afraid of the extent of this issue. LockSupport.parkNanos(..) is basically the root of all other concurrency primitives in the JVM.

It'll be heavily used in the concrete concurrency classes, but not by the actual synchronized keyword.

regards,

  Dr. Richard Warburton
