Subject: [PATCH] Ease ClassLoader Deadlocks Where Possible
|
|
|
|
When on Java 7 we can register the classloader as parallel capable to prevent deadlocks caused by certain scenarios. Due to the nature of PluginClassLoader this isn't completely safe, but we can make it safer by switching to concurrency focused collections. Either way this is far better than crashing the server.
