FULL PRODUCT VERSION :
java version "1.7.0_65"
Java(TM) SE Runtime Environment (build 1.7.0_65-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, midex mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Versdion 6.1.7601]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Using env variable "JAVAWS_VM_ARGS=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=
n,address=5508" to enable debugging of Java Webstart applets. When using 1.7.0_65, the socket is not listening and debug is not possible. Reverting to 1.7.0_60 all works fine.

A DESCRIPTION OF THE PROBLEM :
After upgrading to 1.7.0_65, debugging of java web start applets no longer works.

Determined using "netstat -an" that the socket transport is not listening.

Reverted to 1.7.0_60 (which is what I was running prior) and it works fine (as it had been). Tested by uninstalling/installing two times, and the behavior is consistent.

My environment variable is
"JAVAWS_VM_ARGS=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=
n,address=5508"

Using this debugging on a daily basis, so the issue is not from a new setup/config - the only change is using or not using 1.7.0_65

REGRESSION. Last worked in version 7u60

ADDITIONAL REGRESSION INFORMATION:
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, midex mode)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Set the environment variable as shown.
2) Start a JWS applet
3) "netstat -an"
      3a) with 1.7.0_60 the debug socket is listening
      3b) with 1.7.0_65 the debug socket is NOT listening


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
debug socket should be listening, and thereby remote debugging of the applet should be possible
ACTUAL -
debug socket is NOT listening, and thereby remote debugging of the applet is NOT possible

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
no work around found - had to revert to prior jdk version
