Hi,

STDOUT: Framework launched

According to #507 and http://www.docear.org/support/forums/docear-support-forums-group3/bug-reports-forum6/docear-does-not-start-on-archlinux-thread1583/, it has to do with Java version. But in my case openjdk-jre 8 is activated via asdf locally.

$ java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.242-b08, mixed mode)

Thus it does not seem java version issue in my case. Any input?

Cheers,

SOLVED: Installing Java 7 worked:

# xbps-install -S openjdk7-bootstrap

Once installed, I exported the java environment for the specific instance:

$ JAVA_HOME="/usr/lib/jvm/java-1.7-openjdk/jre" ./docear.sh

It worked.

NB: Docear 1.2 appears not to work with anything above java v7.
