Workaround:

How to add a new Java parameter or value:
1. Navigate 
to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASWEStreamletEngine\Par
ameters"
2. Determine the highest number or value for all the registry entries 
named "JVM Option Number x"     
example: JVM Option Number 18
3. Ensure the value in parenthesis for the "JVM Option Count" registry entry is 
one cardinal number higher than the highest "JVM Option Count" number     
example 0x00000013(19)
4. Now modify the "JVM Option Count" registry entry to the next cardinal number 
(+1) 
example: from 0x00000013(19) to 0x00000013(20)
5. Create a new "String Value" named "JVM Option Number x" where x is the next 
cardinal option number 
example: JVM Option Number 19
6. Modify the newly created string and give it a "Decimal" value (under 'Value 
data') of "-XX:-UseConcMarkSweepGC" (without the quotes)
7. Reboot the server or restart all SWS Services
