Has anyone ever seen an exception thrown when calling close method on any closable object?

Any code can throw an exception: your code, code from a package written by someone else such as the packages that come with the Java platform, or the Java runtime environment. Regardless of what throws the exception, it's always thrown with the throw statement.
The object, called an exception object, contains information about the error, including its type and the state of the program when the error occurred. Creating an exception object and handing it to the runtime system is called throwing an exception.
If you write to a file without closing, the data won't make it to the target file. But after some surfing I got to know that Python automatically closes a file when the reference object of a file is reassigned to another file. It is a good practice to use the close() method to close a file.
Use the close() Method to Close a File in Java.
An IOException will be thrown on close if the final flush fails. Possible causes include:
OutputStreamWriter or similar,I have certainly seen some of these. Others are unlikely.
However, if the data you are writing is important then you should allow for close failing. For example, if your application is writing out a critical file the file system fills up, your application had better notice this before it replaces the old copy of the file with the truncated version.
