Why is this an issue?
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 with the handler is released only at the end of the process.
Noncompliant code example
File file = new File("file.txt");
file.deleteOnExit(); // Noncompliant
