Hello
I tried to start /usr/bin/freemind but it could not find a java: /usr/bin/freemind: Unable to find an appropriate java runtime. See java_wrappers(7) for help
The reason is th usage of '$__jvm_alt' in java-wrappers.sh which is delivered by jvm-list.sh:59
I think that an empty string in '$__jvm_alt' is handed wrong in java-wrappers.sh:125 Additionaly the variable shouldn't be empty.
in jvm-list.sh:59 __jvm_alt=$(readlink /etc/alternatives/java|sed -n 's/\(\/usr\/lib\/jvm\/[^\/]*\)\/.*/\1/p')
> readlink /etc/alternatives/java /opt/Oracle_Java/jre1.8.0_45/bin/java
>__jvm_alt=$(readlink /etc/alternatives/java|sed -n 's/\(\/usr\/lib\/jvm\/[^\/]*\)\/.*/\1/p'); echo $__jvm_alt here we get an empty string >
Without option -n in the sed command everything works well
> __jvm_alt=$(readlink /etc/alternatives/java|sed 's/\(\/usr\/lib\/jvm\/[^\/]*\)\/.*/\1/p');echo $__jvm_alt /opt/Oracle_Java/jre1.8.0_45/bin/java >
why do we need this sed-_expression_ and why the option -n ?
thus
