This problem can be prevented by disabling the shared class cache using -Xshareclasses:none.
When a JVM wants to lock the shared class cache for updating the cache, it must wait for other JVMs to release read-locks on the cache. There is a timeout for waiting, since a crashed or hung JVM may leave a read-lock on the cache. After the timeout, the JVM could assert under certain conditions if the read-locks are not all cleared. In a heavily loaded environment, it can happen there are enough readers attached to the shared cache to exhaust the JVM's timeout period.
This defect will be fixed in: 6.0.1 SR2 7.0.0 SR1 . The timeout for locking the cache has been increased sufficiently to allow existing readers to complete their work. Also this particular assertion has been removed as this condition is not fatal.
