B4J Question B4J Libraries and Java 11+ Compatibillity with previous projects

[ThRuST]

I have installed the latest (at the time posting) B4J v7 and Java 11.

I want to make my huge project Athena compatible with this latest Java version.
That's why I ask the neccessary libraries to be updated to work with the latest Java version.

This is the error I get when I run my project Athena

Libraries used

It used to work with SDK v9.0.4 but as you all understand I have to keep up to date with the latest updates of Java, so I am asking for updates of the included libraries for whom it may concern.

Thanks

Did you install Java 11 from oracle or OpenJDK?

 

[ThRuST]

Oracle JDK v11.0.2 from here

What's OpenJDK and what's the difference? please shed some light on this

 

[OliverA]

You'll have to pay license fees to Oracle to continue using their newest JRE/JDK. Oracle JDK/JRE are meant for paying customers. If you are going for non-license fees, then go with OpenJDK/OpenJFX (https://openjdk.java.net/,https://openjfx.io/).

It is possible that you are using javafx.swing with javaobject, Try searching your source code for javafx.swing

 

[stevel05]

I have only installed jdk-11.0.1 but the version of your software I have (0.97L) compiles here, make sure you have installed the correct javafx version. Unless you have added access to javafx.swing since.

 

[ThRuST]

@stevel05 No I have not added anything else since then. I just upgraded to B4j v7 and installed Oracles JDK v11.0.2, but I guess I should uninstall that

and install the open source version? Perhaps it's that which causing the error message, I'm using the wrong JDK!!?

 

[ThRuST]

@OliverA I had no idea about that Oracle will start charge for using it!!! That's really bad news. I guess the open-source will be the way to go,

or maybe I am missing something important here. In that case just fill me in on that

 

[ThRuST]

Found this on B4j page, OpenjDK11 + OpenjFX 11, totally new stuff but I'll install that then I guess go here

 

[ThRuST]

Btw my project Athena is a commercial project, which means if I succeed we'll all be rich!! lol
Will OpenJDK still be the way to go? it says

License permits usage in closed commercial projects.

what the.. does that mean!!

Some excerpts from Oracle Java License (https://www.oracle.com/technetwork/java/javase/terms/license/javase-license.html):

License Rights and Restrictions

[ThRuST]

I'm speechless!!!! what to say!!? so what about the open source JDK? cannot that be used commercially or what?

What option is leaft for us anyway? I really wonder.

 

[ThRuST]

Maybe I should just uninstall Java 11 and go back to Java v9.0.4!!!!!!!!!

 

[OliverA]

See: https://blog.jetbrains.com/idea/2018/09/using-java-11-in-production-important-things-to-know/. Short answer: Use OpenJDK (if you want free).

 

[ThRuST]

Well I was planning to have Athena distributed with dealers of new laptops... you name it. At least that's a plan.

Until Oracle ruined my vision.

 

[ThRuST]

I must find out what Oracle charge for commercial usage of Java.. and if the two different standards is compatible or not.

We should have known it would come to this sooner or later. Java JDKs was only a plan for them to make money on this technology.

They must keep up with Microsoft because as it is now Bill Gates eats Oracle for breakfast.

 

[ThRuST]

Cannot Java v9.0.4 be installed at the same time as Java 11+ !!!!!!? I mean, if we want to use any program made years ago with the new Java will it be possible?

or else, BIG SHIT!!!

 

[OliverA]

Users can run JRE's as long as they want. They just may not get any updates anymore. Java 9 & 10 only had 6 months life cycles. Oracle's 11 is the new LTS. OpenJDK has a live cycle of 6 months. So after 6 months, the previous OpenJDK will not receive any updates anymore, even if you where willing to pay. If you are willing to pay for updates, then go with Oracle's version. End users of JRE 8 (non-commercial environments) will receive updates until sometime in 2020. Multiple JRE's/JDK's can be installed at the same time.

 

[OliverA]

Please note I may be completely wrong about some of this.

 

[ThRuST]

Well personally I don't care about Oracle's life cycle ideas, as long as we can develope a complete application on Java 8 or 9 for FREE and make it work on any computer, regardless if they have Java v250 commercial installed or not lol
I did install Oracle JDK v11.0.2 while I had JDK v9.0.4 installed and that made my project not run, so if I can just get around this it's peach.
If that will work somehow I'll complete my project using JDK v9.0.4 and I'll be safe all the way to Wallstreet lol
