Do you use the IDE integrated CVS?

The problem is, that after checkout of the project from CVS, the "Generate
Debugging Info" option is set to false!
This is because that information is stored in
nbproject/private/private.properties as javac.debug=true

Java should sync that up somehow, because when the user creates the project,
initially there is "Generate Debugging Info" as true. When they add it to CVS,
delete and checkou again, they get "Generate Debugging Info" as false. This is
very confusing IMHO. What if the private/private.properties are automatically
created with the default content if they do not exist?

I would suggest a different fix: don't touch J2SEProject, remove storage of
initial javac.debug in J2SEProjectGenerator (in fact remove creation of
private.properties altogether), and change build-impl.xsl to define true as the
default value for javac.debug if not explicitly set. Might need to change
something in J2SEProjectProperties to reflect a different value, but I am not
sure. This approach be more reliable and cleaner, and would work for projects
that had not been opened in the IDE (this patch does not).

BTW the attached commit also touches JAVADOC_PREVIEW. Is that intentional? IMHO
javadoc.preview (and application.args) should be handled the same way.

Reopening to fix it in the build script.

The problem with setting properties in the build-impl.xml is that it requires
changes in the customizer. The ToogleButtonModel created by the
StoreGroup.createToggleButtonModel () has value false if the property is not
defined, but in this case we need opposite behavior (true if the property is
missing).
It would require either a compatible API change in the StoreGroup (adding new
factory method), or to copy the model into the j2seproject and modify it there.
The API change is not doable now, so I will create a copy of the model in the
release50 and create a task for the API change in the NB 5.1

I've created task for extending StoreGroup:

What I'm missing from the current trunk patch (both optional I guess but would
be nicer):

1. Handling of application.args. This appears to currently be set to "" in
project.properties *and* private.properties by J2SEProjectGenerator, but changes
go into private.properties (I think). Would suffice to remove all mention of it
from J2SEPG (leave J2SEPP alone) and insert into build-impl.xsl

<property name="application.args" value=""/>

2. This block from J2SEPG could simply be deleted:

ep = h.getProperties(AntProjectHelper.PRIVATE_PROPERTIES_PATH);
ep.setProperty("application.args", "");
ep.setProperty(J2SEProjectProperties.JAVAC_DEBUG, "true");
ep.setProperty(J2SEProjectProperties.JAVADOC_PREVIEW, "true");
h.putProperties(AntProjectHelper.PRIVATE_PROPERTIES_PATH, ep);

I would resolve the additional comments only in the trunk, not in the 5.0
because they shouldn't cause any problems.

Verified in trunk build #200601041900. I agree that just this part will be
integrated to 5.0 branch. Tomasi, please integrate it to 5.0.

I agree with backporting to 5.0.

Verified in trunk.

Integrated into release50
