Possible static issue with BroadcasterFactory

[jfarcand]

Old issue, but can still happen when Atmosphere is embedded

atmosphere/modules/cpr/src/main/java/org/atmosphere/cpr/BroadcasterFactory.java

protected static AtmosphereConfig config;

atmosphere/modules/cpr/src/main/java/org/atmosphere/cpr/DefaultBroadcasterFactory.java

Line 131 in 408f864

b.setBroadcasterConfig(new BroadcasterConfig(config.framework().broadcasterFilters, config, id.toString()).init());

Likely reproducible simply by calling
atmosphere.init(config);
simultaneously from two threads.

At least reproducible by setting a breakpoint in DefaultBroadcasterFactory.lookup(Class,Object,boolean,boolean) and ensuring the “wrong” thread enters the synchronized block first.
