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 trace of /usr/bin/freemind, java-wrappers.sh, jvm-list.sh --------- > DEBUG=script DEBUG_WRAPPER=1 /usr/bin/freemind + [ -n script ] + DEBUG_WRAPPER=1 + export DEBUG_WRAPPER + _source /etc/freemind/freemindrc + [ -f /etc/freemind/freemindrc ] + _source /home/thus/.freemind/freemindrc + [ -f /home/thus/.freemind/freemindrc ] + [ -r /usr/lib/java-wrappers/java-wrappers.sh ] + . /usr/lib/java-wrappers/java-wrappers.sh + . /usr/lib/java-wrappers/jvm-list.sh + dpkg --print-architecture + __arch=i386 + __jvm_default=/usr/lib/jvm/default-java + __jvm_sun6=/usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun + __jvm_sun=/usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun + __jvm_sunmin5=/usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun + __jvm_gcj2=/usr/lib/jvm/java-*-gcj-4.* + __jvm_gcj5=/usr/lib/jvm/java-1.5*-gcj-4.* + __jvm_openjdk6=/usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk + __jvm_openjdk7=/usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + __jvm_gcj=/usr/lib/jvm/java-*-gcj-4.* + __jvm_openjdk=/usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk + __jvm_java7=/usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + __jvm_java6=/usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + __jvm_java5=/usr/lib/jvm/java-1.5*-gcj-4.* /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + __jvm_java2=/usr/lib/jvm/java-1.5*-gcj-4.* /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk /usr/lib/jvm/java-*-gcj-4.* + readlink /etc/alternatives/java + sed -n s/\(\/usr\/lib\/jvm\/[^\/]*\)\/.*/\1/p This value is wrong (empty string) an it is handled wrong later + __jvm_alt= + __jvm_all=/usr/lib/jvm/default-java /usr/lib/jvm/* + [ ] + JAVA_CLASSPATH= + [ ] + DESTDIR= + [ ] + JAVA_JARPATH=/usr/share/java + [ ] + require_java_runtime java6 + find_java_runtime java6 + [ ] + [ ] + [ -z ] + DIRS= + test -z java6 + test java6 + echo java6 + egrep -- [^0-9A-Za-z_] + eval echo -n $__jvm_java6 + echo -n /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + found_jvm=/usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + [ -z /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk ] + DIRS= /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + shift + test + [ -z /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk ] + echo /usr/lib/jvm/java-6-openjdk-i386 /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/j2*1.6-sun /usr/lib/jvm/java-7-openjdk-i386 /usr/lib/jvm/java-7-openjdk + fgrep + JAVA_HOME= + java_debug Picking up the JVM designated by the alternatives system: + [ 1 ] + echo [debug] /usr/bin/freemind: Picking up the JVM designated by the alternatives system: [debug] /usr/bin/freemind: Picking up the JVM designated by the alternatives system: + java_debug JAVA_HOME = '' + [ 1 ] + echo [debug] /usr/bin/freemind: JAVA_HOME = '' [debug] /usr/bin/freemind: JAVA_HOME = '' + [ ] + java_warning No java runtime was found + echo [warning] /usr/bin/freemind: No java runtime was found [warning] /usr/bin/freemind: No java runtime was found + return 1 + java_fail Unable to find an appropriate java runtime.
