JDK-7080020 - Add conventional constructors to InternalError and VirtualMachineError
Description
7080020 adds new constructors to InternalError and VirtualMachineError but as VirtualMachineError doesn't specify its serialVersionUID then it is changed by the addition of these constructors:

JDK7 and older:
java.lang.VirtualMachineError:    static final long serialVersionUID = 4161983926571568670L;

jdk8/tl:
java.lang.VirtualMachineError:    static final long serialVersionUID = -8070910810128390498L;

As most of the errors that extend VirtualMachineError always do not declare a serialVersionUID then their value changes too.

EVALUATION An oversight that highlights to need to build the entire JDK with -Xlint:serial.
