Some implementation was done using OS detection:

But I prefer to stay without any additional args if they don't specified - Java RT works fine
with defaults (at least for me)

> Using my x64 environment I got PermGen space error.
> Sure - I can change JAVA_MAX_MEM, JAVA_PERM_MEM, JAVA_MIN_MEM, JAVA_MAX_PERM_MEM variables.
> But I found that without memory settings [1] my scenario works fine.
> Is it possible to set java memory options only if variables are present?
> 1. set DEFAULT_JAVA_OPTS=-server -Dderby.system.home="%KARAF_DATA%\derby" -Dderby.storage.fileSyncTransactionLog=true
