java-agent to inject system properties on NetBeans startup
Hi all,
What do you think on the idea to create a simple Java agent which can
insert system properties into the JVM before NetBeans starts?
My motivation are the following:
1. Sometimes you need to change some properties to debug NetBeans
behaviour. Copy and change netbeans.conf can be clumsy. (Ok, I know
what I'm doing and it is fine for me, but we have other users.)
2. There can be a situation when some values needs to be computed, like
Java 11 were messing up with font rendering on Linux and there is no
proper default value for the antialiasing property which works on
all platform. Also dpi awareness for HiDPI would requires some logic
as well.
Unfortunately this won't solve the currently quiet bloated command line
in netbeans.conf (just probably reduce it a bit.)
It would be good to be able to set the Memory and GC flags for the IDE
as well (though memory would be sufficient)
What do you think?

Well, my primary intention was to somehow find a solution on the default
value of: |awt.useSystemAAFontSettings|
Which is actually would be a workaround of a JDK 11 bug, not setting
this value correctly on Linux (see:
https://cwiki.apache.org/confluence/display/NETBEANS/Font+Rendering+Issues
).
So this value shall require some initial evaluation. Also there are a
number of properties in netbeans.conf and there is no good programmatic
way you can alter them. Thought of having a property file and a simple
javaagent would be enough.
However thinking this further, probably it would be good to make our
launcher itself smarter and have a different file which can be edited
both by hand and programmatically to provide an UI for all the Java
parameters.
||
I feel the out of the box appearance really important, and having good
default settings is a place we can improve. Any ideas are welcome, as
I've just dropped mine here.

What problem are you trying to solve?
Or, rather, what does this solve that editing netbeans,conf (by hand or
programmatically) it a module that calls System.setProperty()?

Well, that's only true for the Windows launcher AFAIK.
You can file an issue for that, there are a few people working on the
Windows Launcher, they might can help this to happen.

Hi all,
for the most frustating limitation is that in the .conf-file only
${HOME} are ${APPNAME} are substituted. A typical situation in a university context is that
the size of the home-directories are limited because they are saved on a shared harddisk. In
this case I want to switch for the nebeans platform app to an other self defined local folder
which subfolders for each user. To do this I need the possibility to substititue other
environment variables in the conf-file. It would be great to make this possible.
best regards
Oliver

I understand the requirement, but not sure that's a better approach
than providing a UI for editing the user-land .conf file?
eg. http://wiki.netbeans.org/FaqNetbeansConf (that page doesn't seem
to have been migrated)
Best wishes,
Neil
