version 1.6 JMeterThread calls getSampler with entry == null

[asfimport]

Jan Kester (Bug 1292):
Version 1.6a

Trying to get JMeter running with a ThreadGroup, a constant timer, a view
results listener, a once only logic, and a URL sample as a part of the once
only logic controller. URL sample contains an ip, index.html as file, and
method get.
JMeter causes a null pointer exception in
org.apache.jmeter.threads.JMeterThread.getSampler(entry)
In the run method of JMeterThread first a test is done whether entry == null,
but regardless the result of this, the getSampler(entry) method is called. This
method causes an error as a method of entry is called, though the object does
not exist. I guess that if entry equals null, the getSampler method shouldn't
be called.

Severity: critical
OS: Linux

Added a break so that JMeter stops sampling if no more samples are present

Marking all bugs RESOLVED before JMeter 1.8's release date as VERIFIED.
Yes, it's pretty poor QA procedure, but there's bugs here lingering since JMeter
1.6, and we need to clean up a little.
