With SSH slave plugin, I have the following issue:

On the target machine, we still have JDK 1.7 as default java (the software running is rather old). As Jenkins needs 1.8, it is installed in addition to this. I then tried to start the slave, with the following output:

(some ugly shell script code here...)
[06/11/18 16:11:02] [SSH] Starting sftp client.
[06/11/18 16:11:02] [SSH] Copying latest slave.jar...
[06/11/18 16:11:04] [SSH] Copied 767,078 bytes. Expanded the channel window size to 4MB
[06/11/18 16:11:04] [SSH] Starting slave process: cd "/home/baker/jenkins" && /opt/jdk1.8.0_162/bin/java -Xmx1572m -jar slave.jar
bash: /opt/jdk1.8.0_162/bin/java: No such file or directory Slave JVM has terminated.
Exit code=127

That is wondering me, because directory /opt/jdk1.8.0_162 doen't even exist. I also tried to set the JAVA_HOME in the config of the node and also tried to add the JDK7 tool location, but that does not change anything. It would be great if I could configure it here.
