java.io.IOException：从Jackson解析JSON时关闭流

Question

我试图在通过perl转储后解析一个看起来像这样的JSON对象

{
  "customerID":"random",
  "sessionID":"192-3105199-8486749"
}

当我尝试反序列化时，我得到以下异常 -

[tomcat:launch] java.io.IOException: Stream closed

[tomcat:launch] at org.apache.catalina.connector.CoyoteReader.read (CoyoteReader.java:108

我对JSON相当陌生，并且不知道出了什么问题。
