java -version java version "1.3.1_02" Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02) Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode) Runing on Windows 2000 Service pack 2 > I am just setting -Djava.compiler=NONE That was also enough in the good old days :) This is from my 1.3.1_02 javadoc: "The Java HotSpotTM Client VM The Java HotSpot Client VM is the default virtual machine. Its use of Java HotSpot technology gives it superior performance to that of the Classic VM. Unless special command-line options are used to invoke the Classic VM instead (see below), java will always launch an application to run on the Client VM. The Java 2 Classic VM The Java 2 Classic VM is essentially the same virtual machine implementation as in version 1.2 of the Java 2 SDK. It may be invoked by using the -classic command-line option, as in this example: java -classic MyApp The Java 2 Classic VM is included only in the Java 2 SDK. It is not included in the Java 2 Runtime Environment. The -classic option will not work with the Java 2 Runtime Environment." So, even the doc says: To disable HotSpot use -classic, AND it is only possible on the SDK. I also read at some point which I can't find again (nice proof, eh! :) that the JDK in 1.3 will ignore the -Djava.compiler=NONE instruction and still use HotSpot. > > A while ago I posted some fixes/suggestions for changes in JDE to ensure that > > debugged applications started from JDE ran in classic mode, but I do not know > > if these changes have made it into the codebase yet.... > > Do you have this documented anywhere? What was the subject line? Here is some trace of it. http://www.mail-archive.com/jde@sunsite.dk/msg02979.html Maybe it has been fixed - can't remember it.
