NPE during GUI launch on latest trunk
Hi all
I just tried to run `ant run_gui` on the latest (github) trunk but
this results in an NPE - specifically when trying to create the
JMeterTreeModel.
Any ideas?
Thanks
Graham

I get the same, after I switched to gtk+ in the menu and restarting jmeter.

Thanks!
I found the following references:
https://www.securecoding.cert.org/confluence/display/java/MET05-J.+Ensure+that+constructors+do+not+call+overridable+methods
https://dev.eclipse.org/sonar/coding_rules#rule_key=squid%3AS1699|s=createdAt|asc=false
Might be an idea to add those to the bug report.

Yeah, I realise now that will only help sub-classes of NamePanel.
But it still needs to be fixed.
I had not considered that the JVM would have the same fault.

Not necessary unless setName() is called by the JPanel ctor directly
or indirectly.

That seems to be the case here.
However I'm not sure that there any guarantees of the order of initialisation.
What is guaranteed is that initialisation will be completed when the ctor exits.
Whilst the ctor is still being executed there's not telling what state
classes will be in.

It does look as though the GTK+ ctor calls an overrideable method.
So it is broken; the problem needs to be reported and fixed as it
won't only affect JMeter.
It's not possible for subclasses of JPanel to reliably fix the problem
since there's no knowing what parts of the class have been initialised
and which have not.
The best subclasses can do is add protection against some failures,
such as the NPE here.
But that is a hack, and should not be released unless absolutely necessary.
And in that case the code must be carefully documented to explain why
the code does what it does and when the work-round can be removed.
Also, the fact that the ctor calls getName presumably means it needs
to obtain the value in order to complete its own init.
How does the subclass return the correct value?

So, if I understand it correctly. The superclass will get initialized
before ourselves and that ctor will call into the laf system, which
calls the getName method (which we have overridden). At that time (init
of ctor of super) our fields will not have initialized, which leads to
the NPE.
So, I think the problem lies in the gtk+ implementation of laf, which is
calling an overridable method in the ctor.

Your analysis is correct, that setName should not be used in the ctor as it could be modified in subclasses.
I tried a variant first, where I inlined the functionality of setName into the ctor.
That didn't help.
We could add a safe guard into setName just in case and for symmetry.

I doubt that this is the full solution.
If the nameField can be null here then it can perhaps be null in setName.
The underlying cause of the issue needs to be found.
One problem I notice is that the NamePanel ctor calls setName() which
can be overridden - that can cause issues because the object won't be
fully constructed until the ctor completes.
This is why init() is private.
The setName() code either needs to be duplicated in init(), or it
could be put into a private method called by the ctor and the public
setName.

Re: NPE during GUI launch on latest trunk
Posted by Philippe Mouawad <ph...@gmail.com>.
Hi Graham,
It could be coming from a Sonar error I fixed in r1783482
@Override
public String getName() {
if (nameField != null) {
return nameField.getText();
}
return ""; // $NON-NLS-1$
}
Could you try it ?
Thanks
