Can I kill a java thread from JDB?

2020-08-02 • Java

In theory, JDB (@l)u 419)u 0@ debugger) allows you to kill a single thread In practice, is it possible? Here, I attach JDB to my JVM, which has an agentlib on port 8000:

$jdb -attach 8000
>

I listed the topics:

> threads
Group system:
  (java.lang ...
  [...]

I found the thread in question and tried to kill it:

> kill 0x21bb new java.lang.Exception("die!")
killing thead: pool-766-thread-1
> com.sun.tools.example.debug.expr.ParseException: Unable to create java.lang.Exception instance
Expression must evaluate to an object

So threads can't be killed?

How to create a new exception in JDB and let it kill the thread?
