Not to be a nag here, but VirtualMachineError javadoc says "Thrown to
indicate that the Java Virtual Machine is broken or has run out of
resources necessary for it *to continue operating*.", and
OutOfMemoryError extends VME. It is true that it is a transient
failure in many circumstances, but if its impossible to find out, for
an application, what the circumstances and implications are, along
with whether these errors are even being thrown around, what should
the application do?
