Title: Message Title

Stefan Kaltenberger created an issue   Jenkins / JENKINS-53245 UnsupportedOperationException when setting JAVA_HOME Issue Type: Bug Assignee: Ivan Fernandez Calvo Components: ssh-slaves-plugin Created: 2018-08-27 08:02 Environment: Jenkins 2.140 / SSH Slaves Plugin 1.27 Labels: plugin regression Priority: Minor Reporter: Stefan Kaltenberger The usage of the environment variable JAVA_HOME (set via Node Properties) to specify the Java installation path results in the following exception when connecting: ERROR: Unexpected error in launching a agent. This is probably a bug in Jenkins. java.lang.UnsupportedOperationException {{ at java.util.AbstractList.add(Unknown Source)}} {{ at java.util.AbstractList.add(Unknown Source)}} {{ at hudson.plugins.sshslaves.DefaultJavaProvider.lookForJavaHome(DefaultJavaProvider.java:94)}} {{ at hudson.plugins.sshslaves.DefaultJavaProvider.getJavas(DefaultJavaProvider.java:76)}} {{ at hudson.plugins.sshslaves.JavaVersionChecker.resolveJava(JavaVersionChecker.java:72)}} {{ at hudson.plugins.sshslaves.SSHLauncher$2.call(SSHLauncher.java:851)}} {{ at hudson.plugins.sshslaves.SSHLauncher$2.call(SSHLauncher.java:821)}} {{ at java.util.concurrent.FutureTask.run(Unknown Source)}} {{ at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)}} {{ at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)}} {{ at java.lang.Thread.run(Unknown Source)}} I guess this is related to the following code, which tries to add a path to an immutable list:   private List<String> lookForJavaHome(Node node) { List<String> ret = Collections.emptyList(); if(node != null && node.getNodeProperties() != null){ for (NodeProperty property : node.getNodeProperties()){ if(property instanceof EnvironmentVariablesNodeProperty){ EnvVars env = ((EnvironmentVariablesNodeProperty) property).getEnvVars(); if (env != null && env.containsKey(JAVA_HOME)) { ret.add(env.get(JAVA_HOME) + BIN_JAVA); } } } } return ret; } https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/src/main/java/hudson/plugins/sshslaves/DefaultJavaProvider.java Add Comment   This message was sent by Atlassian Jira (v7.11.2#711002-sha1:fdc329d) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
