Java language specification [20.20.39 public static void sleep(long millis)
throws InterruptedException] says:

"If the current thread is interrupted (20.20.31) by another thread
while it is waiting, then the sleep is ended and an
InterruptedException is thrown."

The following example shows that InterruptedException is not thrown.
The statement
out.println ("InterruptedException 1");
in catch block is not executed:

> javac -d . excp02509.java
> java javasoft.sqe.tests.lang.excp025.excp02509.excp02509
1-1 before sleep is interrupted false
  2-1 is interrupted false
  2-1 is alive true
  2-2 is interrupted true
  2-2 is alive true
1-2 after sleep is interrupted true
