Use of File.deleteOnExit() is not recommended for the following reasons:

 The deletion occurs only in the case of a normal JVM shutdown but not when the JVM crashes or is killed.
 For each file handler, the memory associated to the handler is released only at the end of the process.

Noncompliant Code Example

File file = new File("file.txt");
file.deleteOnExit();  // Noncompliant
