java - Who interrupts my thread?

Question

I understand what an InterruptedException does and why it is thrown. However in my application I get it when waiting for SwingUtilities.invokeAndWait() on a thread that is only known by my application, and my application never calls Thread.interrupt() on any thread, also it never passes the reference of the thread on to anyone.

So my question is: Who interrupts my thread?

Is there any way to tell? Is there a reason why the InterruptedException doesn't contain the name of the Thread that requests the interrupt?

I read that it could be a framework or library that does this, we use the following, but I can't think of reason for them to interrupt my thread:

• Hibernate
• Spring
• Log4J
• Mysql connector

If possible, you could extend Thread and overwrite the interrupt() method for this thread to print a stacktrace or throw an unsupported operation exception.

You could also use the extended Thread class to store a reference to the interrupting thread and read it once you catch the interrupted exception.
