Groovy while loop not executed correctly

问题

I've following simple while loop code in groovy -

def count = 1
while(count <= 5) {
    println "$count"
    sleep(5000)
    println "Sleeping for 5 seconds"
    count++
}

Which indicates that loop is executed only twice still second time Sleeping for 5 seconds is not run. Actually with this code, while block is expected to be executed 5 times. Can someone help to understand why such a weird behaviour?

When this code is run, output is following -

1
Sleeping for 5 seconds
2

This works fine:

~ $ cat doit.groovy 
def count = 1
while(count <= 5) {
    println "$count"
    sleep(5000)
    println "Sleeping for 5 seconds"
    count++
}
~ $ groovy doit
1
Sleeping for 5 seconds
2
Sleeping for 5 seconds
3
Sleeping for 5 seconds
4
Sleeping for 5 seconds
5
Sleeping for 5 seconds
