I have SmartSvn 6.6.7 working fine with it. You need to use SET JAVA_OPT=%JAVA_OPT% "-Dsmartsvn.checkIncompatibleJava=false" or it will fail.To get it to work on SMP you need to set all the JAVA exes to use only one processor. This is true for JAVA 1.42 also. SmartCVS still works with JAVA 1.42 so the Dsmartsvn.checkIncompatibleJava=false switch doesn't appear to be available resulting in SmartCVS failing to load.
