Different application instances are usually deployed with different class loaders, so that they are completely independent from each other, including any static content. For example, if there are two instances, they will not know about each other's Ignite instances. Each of them should start Ignite on its own.
Nature of your exceptions is not clear to me though. It looks like classpaths interfere with each other somehow which is weird. I would check JBOSS deployment model and settings. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Runtime-error-caught-during-grid-runnable-execution-GridWorker-tp11016p11736.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
