#2631 Version 1.7.x says "Java 10 not supported" at launch time

[Neo]

Like the title says, I'm unable to launch FP. On Windows 10.

[Felix Natter]

hi Neo,

unfortunately, jre10 contains a bug which is why it cannot be supported by Freeplane.
Please uninstall jre10 and install jre11.

Cheers and Best Regards,
Felix

I get the same message on Linux on startup, but I already have JRE 11 installed. At least, I have "openjdk-11-jre" installed, which is the latest version of openjdk available.

If I run "java --version" I get:

openjdk 10.0.2 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4, mixed mode)

Hm, looks like I actually have version 10, strange packaging thing - https://askubuntu.com/questions/1037646/why-is-openjdk-10-packaged-as-openjdk-11

[Fygul Hether]

For Ubuntu 18.04:

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt install openjdk-11-jre

It's real version 11

[Luke Plant]

Thanks so much Fygul, this solved my problem.

Do I have to uninstall my java10 first?

[Dimitry Polivaev]

No

[Felix Natter]

hi Luke,
did you activate the openjdk-11-jre with "sudo update-java-alternatives --list/--set"?

Cheers and Best Regards,
Felix

[Tom Williams]

Fygul, I ran the three commands, and everything seems OK. At least it installs, and opens. Thank you.

Win 10 pro
Java 8 - 152
Freeplane 1.7.6

I am seeing the quoted text, "freeplane is not compatible with Java 10", from the shortcut startup

Cygwin:freeplane.sh -- Error: Unable to access jarfile /cygdrive/c/Program Files/Freeplane/freeplanelauncher.jar
Cygwin: freeplane.bat -- works
Cygwin: freeplane.exe -- not compatible error

CMD: freeplane.exe -- not compatible error
CMD: freeplane.bat -- works

[Volker Börchers]

Hi Ted,

if Freeplane generates the incompatibility error then it actually picks up a Java version 10. On Windows better stick to .bat or .exe and resolve the PATH i.e. ensure that Java 10 does noch occur first in your PATH. Also watch out for the variable JAVA_HOME.

How does the .exe track down the Java version? I do have a Java 10 on my hard drive but there is no reference to it. Other than the path there is no environment that references Java. If you want to give me a few hints, I can try looking in the code.

I don't understand: Do you have Java 10 in the path variable or not? The simplest would be to uninstall Java 10 and to install 11.

Volker

[Ted Stockett]

Sorry for the confusion. Java 10 is not in the path variable. There is no reference to it in the environment.

What I tried to say, not very well, was that there is a java in my PATH but it points to a Java 8.

java -version

java version "1.8.0_152"
Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)

We will be installing Java 11 soon but for the time being Java 8 is what I need on my machine. As I pointed out before, the Java 8 seems to be working fine with Freeplane if I start it directly from the jar with the .bat file.

Windows exe is based on launch4j and checks windows registry.
Anyway you could install Java11 as your default java.

You can also set environment variable FREEPLANE_JAVA_HOME as described at https://www.freeplane.org/wiki/index.php/Command-line_options_and_configuration#Select_Java_installation_used_to_run_Freeplane
