EAP 7 creates too many jaeger threads during start up

Issue

• Trying to start JBoss, we reach OutOfMemoryError: unable to create new native thread because thousands of jaeger threads like below are created:

"jaeger.RemoteReporter-FlushTimer" #5976 daemon prio=5 os_prio=0 tid=0x000055cc87bad800 nid=0xa7e1 in Object.wait() [0x00007f85fc4fb000]
