What is Green Thread

Dhananjay Singh

Dear All,

There are lot of questions in mind regarding Green Thread.

I'd like to know what is green thread? What is the difference between
Green Thread and Native Thread? On linux platform which one is good
and why "java -green" command is not working on the linux (using
j2sdk1.4.2_05 for linux).
And above all of these question .........
Why java.sun.com doesn't have any good article for green threads. if u
know kindly provide me the URL.

An early response is requested. Thanks in advance.

Dear Silvio,

If you forget your past, you can't make your future. :)

Any way, one of my client is using some network security application
written in Java & C++. They are having some problem with Green
Threads. We've to identify it and fix it. We can't say them to forget
the Green Threads coz that is old technology.

Is any one have some Idea about Green Threads?

JDK 1.4 no longer contains the Classic JVM which is required to run Green
Threads. If you want to use green threads you'll have to drop back to an
older version and run with the -classic option

In particular this bit might be relevent to you since you mention the app
uses both Java and C++ (JNI?)

"A Java thread supported under green threads cannot call directly into a
non-green-thread enabled library because the latter may itself call a system
call that would cause the underlying kernel thread to wait, thus suspending
execution of the entire Java virtual machine"
