[ https://issues.jboss.org/browse/JBIDE-17700?page=com.atlassian.jira.plugi... ] Fred Bricon commented on JBIDE-17700: ------------------------------------- [~olpf] : does your project use truezip by any chance? Do you use Maven to build your project? If yes, could you attach a copy of your effective pom.xml (after sanitizing/anonymizing any sensible data) [~rob.stryker] : TrueZip 7.x changed their internals pretty significantly. (See https://java.net/projects/truezip/sources/v7/content/truezip-driver/truez..., https://java.net/projects/truezip/sources/v7/content/truezip-driver/truez..., https://java.net/projects/truezip/sources/v7/content/truezip-kernel/src/m...). The new architecture may fix (hide) the reported error ... or not. Might be a good idea to see if we could integrate the latest version (Everything is now split in different jars, so it may not be trivial). Anyways, even if moving to TZ 7.x fixed the error, that wouldn't explain nor fix the inherent Classloader leakage. -- This message was sent by Atlassian JIRA (v6.2.6#6264)
