How to run old school Java programs with latest Java LTS 11?

Question

I want to run Siemens LOGO Soft Comfort.

dell@dell-Precision-M6400:~/Hämtningar/Logo 6.1/Linux/tools/Application$ ./LOGOComfort 
Unrecognized option: -Xincgc
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
dell@dell-Precision-M6400:~/Hämtningar/Logo 6.1/Linux/tools/Application$

This is Siemens LOGO soft comfort 6.1 and I have a license for that. But I have an issue.

Unrecognized option: -Xincgc

So how can I do so latest Java LTS 11 can work with Java from 2008? I assume that is Java SE 6 or J2SE 5.0.

With LOGO software, it comes with two folders bin and lib

Update:

I removed the -Xincgc in LOGOComfort.lax file and now I got this

dell@dell-Precision-M6400:~/Hämtningar/Logo 6.1/Linux/tools/Application$ ./LOGOComfort 
Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)

Update:

Solution:

Remove -Xincgc
Use Java 8 instead. It requries Swing. Java 11 does not use Swing

Why you don't install an old java version? You can easily have many java versions on the same physical machine. — Davide Lorenzo MARINO, Sep 04 '20 at 11:38
`LOGOComfort` is likely a shell script, so edit the script and remove the offending option. — Andreas, Sep 04 '20 at 11:39
As there is a folder named "Applet" - if you want to run applets, you will need an ancient browser version or a dedicated applet-viewer (such as the one that came with old versions of the JDK) — Hulk, Sep 04 '20 at 11:42
Is there a way to search for `-Xincgc` in linux shell terminal? — euraad, Sep 04 '20 at 11:43
Yes, and you'd know that if you did a web search: [`search for text in files in linux shell terminal`](https://www.google.com/search?q=search+for+text+in+files+in+linux+shell+terminal) — Andreas, Sep 04 '20 at 11:44
@Andreas I found `-Xincgc` now in `LOGOComfort.lax` file. I removed it and got this as above. — euraad, Sep 04 '20 at 11:46
Wonder why code running on Linux is trying to use a Windows-only class like `WindowsLookAndFeel`. Seems you need to install an older version of Java, i.e. a version that the Logo is compatible with. Or upgrade to a newer Logo version. — Andreas, Sep 04 '20 at 11:51
@Andreas You're rigth. I will think that I will install Java 6. But do I need to remove Java 11 then? — euraad, Sep 04 '20 at 11:54
@DanielMårtensson no need to remove the newer version - Java versions can coexist just fine. You'll have to specify the path to the one you want to use explicitly, however. — Hulk, Sep 04 '20 at 13:03

open the file 'LOGOComfort', as it is likely a shell script. Find the -Xincgc option and remove it.

If it's gobbledygook, install a java6, which does have the now removed -Xincgc option.

If that's not an option, make a fake java: Make a script that rests at the 'real' java location, and all it does is scan for all command line args, strip -Xincgc from it, and pass the rest through unmolested to the real java. This is a crazy hack and is likely to break other things, but it will probably 'fix' this. I strongly recommend you go with one of the first 2 options first.

There is no way to tell java 11+: Can you 'support' the -Xincgc option.

The error message is saying that it can't find the look and feel profile associated with Windows.

java.lang.NoClassDefFoundError: com/sun/java/swing/plaf/windows/WindowsLookAndFeel

Clearly, this app was intended for Windows in the past. Maybe the script changes the look and feel profile, but I couldn't tell you without looking at it.

Best bet is try this on a Windows machine and see if it goes any further. If not then you'll have to try it with an older JRE that supports that, such as JRE 6.

Can I install Java 6 without removing Java 11? – euraad Sep 04 '20 at 11:56
I want to use Java 11 as default – euraad Sep 04 '20 at 11:56
Yes, as mentioned above, you can have multiple instances of Java installed on the same computer. – Setherith Sep 04 '20 at 12:01
OK. Now I have Java 6 at `/usr/lib/jvm` – euraad Sep 04 '20 at 12:19

I know this is a old question, but I still have a solution that may work (it worked for me). You need to make the application java executable by

chmod a+x $PATH_TO_LOGO/Application_64/jre/bin/java
