org.apache.catalina.connector.CoyoteOutputStream cannot be cast to java.io.ByteArrayOutputStream

This error occurs when you try to cast an object of type CoyoteOutputStream to an object of type ByteArrayOutputStream.
The CoyoteOutputStream is a class that is used by the Tomcat server to write response data to the client. On the other hand, ByteArrayOutputStream is a standard Java class that is used to write data to an array of bytes.
The reason for this error is that CoyoteOutputStream is not a subclass of ByteArrayOutputStream and cannot be cast to it.
To resolve this error, you need to use the appropriate class for the type of data you are working with. If you are working with response data in Tomcat, you should use CoyoteOutputStream. If you need to write data to an array of bytes, you should use ByteArrayOutputStream.
