__jvm_alt=$(readlink /etc/alternatives/java|sed -n
's/\(\/usr\/lib\/jvm\/[^\/]*\)\/.*/\1/p')
Reason is that bacause sed expression did not match path in /opt/..., no
substitution is made, and such sed statement prints pattern space only
if substitution is made.
Therefore in /usr/lib/java-wrappers/java-wrappers.sh fgrep in following code
always succeeds and JAVA_HOME is set to empty:
- if echo $DIRS | fgrep $__jvm_alt /dev/null ; then
- JAVA_HOME=$__jvm_alt
- java_debug Picking up the JVM designated by the alternatives
system:
- java_debug JAVA_HOME = '$JAVA_HOME'
- else
+ if echo $DIRS | fgrep $__jvm_alt /dev/null ; then
+ JAVA_HOME=$__jvm_alt
+ java_debug Picking up the JVM designated by the alternatives system:

+ else
- # And pick up the first one that works reasonably
- for dir in $DIRS; do
- if [ -x $dir/bin/java ]; then
- JAVA_HOME=$dir
- break;
- fi
- done

+ # And pick up the first one that works reasonably
+ for dir in $DIRS; do
+ if [ -x $dir/bin/java ]; then
+ JAVA_HOME=$dir
+ break;
+ fi
+ done
+ fi
This eventually leads to this abnormal exit:
- if [ $JAVA_HOME ] ; then
- # ... omitted ...
- else
- java_warning No java runtime was found
- return 1;
- fi
+ if [ $JAVA_HOME ] ; then
+ # ... omitted ...
+ else
+ java_warning No java runtime was found
+ return 1;
+ fi
Hence other packages that use java-wrappers, e.g. freemind, experience
other failures because java-wrappers failure. In example of freemind, it
will not start at all.
