A @Factory method keeps other methods waiting in EAP 5.1.2

Issue

A @Factory method keeps other @Factory methods waiting.

In thread dumps, the method was locking in getInstanceFromFactory method.

at org.jboss.seam.Component.getInstanceFromFactory(Component.java:2093)
- locked <0x00000006f32a7e48> (a java.lang.Class for org.jboss.seam.Component)

So other threads waitng for release the lock.

java.lang.Thread.State: BLOCKED (on object monitor)
 at org.jboss.seam.Component.getInstanceFromFactory(Component.java:2056)
 - waiting to lock <0x00000006f32a7e48> (a java.lang.Class for org.jboss.seam.Component)
