SessionImpl.flush() has thrown a NullPointerException

Thrown when an application attempts to use {@code null} in a case where an object is required. These include:
  • Calling the instance method of a {@code null} object.
  • Accessing or modifying the field of a {@code null} object.
  • Taking the length of {@code null} as if it were an array.
  • Accessing or modifying the slots of {@code null} as if it were an array.
  • Throwing {@code null} as if it were a {@code Throwable} value.

Applications should throw instances of this class to indicate other illegal uses of the {@code null} object. {@code NullPointerException} objects may be constructed by the virtual machine as if {@linkplain Throwable#Throwable(String, Throwable, boolean, boolean) suppression were disabled and/or the stack trace was not writable}. @author unascribed @since JDK1.0
