Description

Original: About half of the times Jenkins fails to start. The web UI displays: {{java.lang.NoClassDefFoundError: Could not initialize class hudson.model.Hudson$MasterComputer}} {{ at jenkins.model.Jenkins.createComputer(Jenkins.java:3222)}} {{ at hudson.model.AbstractCIBase.createNewComputerForNode(AbstractCIBase.java:162)}} {{ at hudson.model.AbstractCIBase.updateComputer(AbstractCIBase.java:148)}} {{ at hudson.model.AbstractCIBase.access$000(AbstractCIBase.java:48)}} {{ at hudson.model.AbstractCIBase$2.run(AbstractCIBase.java:254)}} {{ at hudson.model.Queue._withLock(Queue.java:1398)}} {{ at hudson.model.Queue.withLock(Queue.java:1274)}} {{ at hudson.model.AbstractCIBase.updateComputerList(AbstractCIBase.java:240)}} {{ at jenkins.model.Jenkins.updateComputerList(Jenkins.java:1670)}} {{ at jenkins.model.Jenkins.<init>(Jenkins.java:1023)}} {{ at hudson.model.Hudson.<init>(Hudson.java:86)}} {{ at hudson.model.Hudson.<init>(Hudson.java:82)}} {{ at hudson.WebAppMain$3.run(WebAppMain.java:298)}} {{Caused: hudson.util.HudsonFailedToLoad}} {{ at hudson.WebAppMain$3.run(WebAppMain.java:312)}} The log contains dozens of exceptions and stacktraces. Restarting often resolves the problem until the next time the service is restarted. This occurred after upgrading from 2.263.3 to 2.303.1
