Java 8 Prompts for Incoming Network Connections

[michaelt]

For now we can keep it in the open - no 'hidden' stuff to help intruders yet.

Until recently this was just a limited system where I used WaterRoof & ZenMap to close the doors. With the emergence of PF and IceFloor to 'manage' it, things got ugly. I have not yet fully understood the PF operation nor IceFloor operation. So I deinstalled IceFloor - no change. Now I need to research deeper into PF and what IceFloor may have modified or left behind.

Now only the OSX firewall should be in control. Turn off - passed. Allow each UMS incoming connections specifically - failed. I opened up all the apps specifically disabled - failed.

In an attempt to track down this and a few other issues I am creating a local sandbox in the hope I can narrow the search. Got my problems there too. Don't know Netbeans but possible.

With the help of the sandbox and WireShark, I hope to nail down the network port requirements (usage) and harden this against intrusion. Security here is major concern.

[michaelt]

Well, no as i only have Netbeans (IDE to build UMS), dmgCreator, and Filezilla installed on my OSX

Created my sandbox, almost looked real good until a few bizarre messages along the way.
Used the Build link first, step by step.. Seemed simple but got error message about missing/bad(?) module and Java. Went to Oracle to get latest Java 8 (highly recommended for security reasons - I listen). Seeing your note about NetBeans and the combo NetBeans/Java8, I installed it. Looked good, aded the UMS project, Clean Build, three Warnings, "BUILD SUCCESS" but the target ums won't execute. Looks like it launches but then nothing.

Tried "Building the Mac OS X installer tarball". Looks like it launches but then nothing - just dies - nothing visible. It doesn't even open the log. (So close but so far away)

At this point I am not sure if I corrupted the install because of the order of the installs. Any help or pointers will be greatly appreciated. I have a few code points I would like to meter in hopes of root causing this a a couple of other issues.

Should we move this to the "Developer" or "Beta Build" forum or just continue here?

[Optimus_prime]

So if your looking to build Java8 or 7 versions of UMS there are alot of things you will need to do to do it.
I can explain it all but it'll take me a little bit to compile and show you how to do it (I use a UMS only Java Launcher thats needed to launch Java 7/8 versions).
Let me know and i'll start typing it up in a few posts.

Should we move this to the "Developer" or "Beta Build" forum or just continue here?

We can leave it here for now as it's OSX only.

If your building Java 6 versions you need to install Java 6 then it'll build without doing anything special
get it from here https://support.apple.com/kb/DL1572?locale=en_US in this update pack

[michaelt]

Thanx - I appreciate the help. I want to stick with J8 since J6 does not have the Network issue and I am security sensitive.

Tried this - same problem: app launches & dies a few seconds later. ????

Also is it possible to have both Java 6 & 8 sandboxes in NetBeans or is Java version system wide option only?
Maybe asked another way: is the build dependent on the system installed Java version?

I am not Java fluent yet but working on it.

[michaelt]

OK - been working with this for while, made progress, made regression.
Tried backing off to J6 - probably wrong way but NB seemed to build it OK but the app would not launch.
Made a few mods, NB is very helpful in getting all the pieces in place before the build. First time using it - nice.
Then the bad - had to go up to the village - came back - NB hung! Could not select anything, hovering produced empty popups.
All failed - had to log out all & reboot. NB would not launch - just bounced in the dock for ~1min & died.
Saved off the modified files, reinstalled all from scratch (probably the wrong way). Then merged the changed files & build clean. Failed - three errors which on the surface look like a broken tree (see below).
Shutting down my brain and eyes. Will reattempt in the morning - clean & reload - no mods first.

Making slow progress and could really use some guidance. Haven't had this much trouble since hpux.

Please advise - I'm listening - thanx.

Had to reboot to recover the inactive memory, then NB indicated some 14 updates, did them, clicked Build and success:

… but it won't launch.
I don't understand why it just started to work.
Better but not there.

[Optimus_prime]

Ok so i should have been more clear. NB is only so you can build your own versions which java 6 should be fine and needs no custom app launchers.
Now you've had success in building your own version, are you launching UMS form the .dmg it makes for you?
Also have you done this from a command prompt

mvn com.savage7.maven.plugins:maven-external-dependency-plugin:resolve-external
mvn com.savage7.maven.plugins:maven-external-dependency-plugin:install-external

its straght out of the pom.xml

I am Java 8 so as to also track down the access permission and port issues.

are you launching UMS form the .dmg it makes for you?

No - I launched directly from:

Screen Shot 2015-04-26 at 9.29.45 AM.png (45.41 KiB) Viewed 11314 times

I did not see a way in NB to build the package.
I tried: "mvn package -P osx" but no "*.dmg" anywhere in my user tree.

Also I loaded the NB-Java8 package directly from Oracle.

Also have you done this from a command prompt

mvn com.savage7.maven.plugins:maven-external-dependency-plugin:resolve-external
mvn com.savage7.maven.plugins:maven-external-dependency-plugin:install-external

Yes - I believe it solved the early build issues.
Is it needed after every NB-Java install or just after getting the UMS tree?

Lastly:
- if I save aside my modified files, do I just copy them back after a clean source download?
- does NB automagically sync from the backing tree in realtime?
- how do you merge in changes from the backing tree?
- do you build from inside NB or CLI (command prompt)?
