#4124 jEdit Won't Load when $JAVA_HOME is set
When $JAVA_HOME is defined in .bashrc
jpolanik@Jill:~/Documents/myRaku/PDF_Tool$ which java
/usr/bin/java
jpolanik@Jill:~$ echo $JAVA_HOME
/usr/bin/java
jpolanik@Jill:~$ jedit
/home/jpolanik/bin/jedit: 24: exec: /usr/bin/java/bin/java: not found
jEdit does not load at all
When $JAVA_HOME is not defined in .bashrc
jpolanik@Jill:~$ echo $JAVA_HOME
jpolanik@Jill:~$ jedit
Warning: $JAVA_HOME environment variable not set! Consider setting it.
Attempting to locate java...
Found a virtual machine at: /usr/bin/java...
jEdit loads and appears to run as expected; but, without $JAVA_HOME other java apps may have a problem.
I'm running Ubuntu 22.04.2 LTS on an Intel processor, with:
openjdk version "19.0.2" 2023-01-17
OpenJDK Runtime Environment (build 19.0.2+7-Ubuntu-0ubuntu322.04)

What's in your ~/bin/jedit file? Is that a shell script to start jEdit?
Yes, ~/bin/jedit is the application launcher that came with jEdit
!/bin/sh
Runs jEdit - Programmer's Text Editor.
Find a java installation.
if [ -z "${JAVA_HOME}" ]; then
echo 'Warning: $JAVA_HOME environment variable not set! Consider setting
it.'
echo ' Attempting to locate java...'
j=
which java 2>/dev/nullif [ -z "$j" ]; then
echo "Failed to locate the java virtual machine! Bailing..."
exit 1
else
echo "Found a virtual machine at: $j..."
JAVA="$j"
fi
else
JAVA="${JAVA_HOME}/bin/java"
fi
Launch application.
exec "${JAVA}" -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true -jar
"/home/jpolanik/jEdit/5.6.0/jedit.jar" -reuseview "$@"

Okay, thanks for drawing my attention to the application launcher, Dale.
The problem goes away when I replaced the original line
JAVA="${JAVA_HOME}/bin/java"
with
JAVA="${JAVA_HOME}"
I dont have Ubuntu 22, but in Ubuntu 20 it works as deployed. I will
verify when I get to work.
JAVA_HOME should be the jdk-19 folder, and not the jdk-19/bin or
jdk-19/bin/java as it appears to be here.
Of course in Ubuntu theres a layer of indirection with the debian
application symlinks.
OR the jdk19 install did something different? It would not surprise me if
Oracle changed a 30yo directory layout just to jerk with everyone.
How did you install the jdk?

Bugs:
#4124Joe,
I installed the JDK by installing the Ubuntu package. There is a certain amount of indirection involved here.
which java returns /usr/bin/java which is a link to /etc/alternatives/javawhich is a link to /usr/lib/jvm/java-19-openjdk-amd64/bin/java.

Closing as the OP fixed the problem. This issue really isn't a jEdit problem anyway, it's the Ubuntu packaging that has problem. I don't know who maintains the Ubuntu package, but that's where the real fix should be.
