ADDITIONAL OS VERSION INFORMATION :
Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u1 x86_64 GNU/Linux


EXTRA RELEVANT SYSTEM CONFIGURATION :
Amazon Web Service
TimeZone S.O.: America / Santiago
JBossAS [6.0.0.Final "Neo"]
Ehcache 2.4.0

A DESCRIPTION OF THE PROBLEM :
Update the JDK's timezone configuration with the tzadata16c from IANA's site, for apply the change "Chile reverts from permanent to seasonal DST." briging to application server not accepted anymore request, the system is like if it's bringing down, but the proccess running anyway.
The probblem occurrs only with the software uses date near from the change to summer schdule for Chile (e.g. 13th August)

ACTUAL -
The system use the CPU's running are jumping to 100% and when I get a thread dump, this one piece of code is constantly blocked at exactly the same place. (All the others are locked and waiting.)

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
with anotherr prior timezone of Iana (e.g. tzdata2016b) the system runs OK always. The latest timezone data all produces the same resulta.
