This class provides the interface and mechanism for plugging VMs into the system. Typically you only need to add a new implementation if your supported attributes or command line building are different from those that exist.

this class has fields for all options that a JDK VM can take, that is the reference point for all others. Note some VMs (like jview) don't take all options and will ignore them (like -mx). Defining the system property "verbose" to 1 will give you warnings for ignored properties in a properly implemented subclass.

here is the canonical output from java -help for options we take:

 -noasyncgc        don't allow asynchronous garbage collection -verbosegc        print a message when garbage collection occurs -noclassgc        disable class garbage collection -ss       set the maximum native stack size for any thread -oss      set the maximum Java stack size for any thread -ms       set the initial Java heap size -mx       set the maximum Java heap size -classpath  list directories in which to look for classes -prof[:]    output profiling data to .\java.prof or .\ -verify           verify all classes when read in -noverify         do not verify any class -nojit            turn off the jit -Dprop=name       define property; can be specified more than once
