Answer 1

Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

您可能有Accounts.class的旧副本浮动，或者在运行时类路径中的多个jar中定义不同。
