Java creator trying to win the stupidest statement award of the year

Can one block assemblies containing "unsafe" code in .NET? I believe you can block JNI stuff in Java. -- My name in Katakana is ヨルゲン. My name in German is Jörgen. I blog too now[^]
Yes, unsafe code is blocked by default if run remotely. That's the purpose of 'unsafe' blocks. Christian I have several lifelong friends that are New Yorkers but I have always gravitated toward the weirdo's. - Richard Stringer

What Gosling is trying to say is probably that a mixed mode app/DLL is unsafe because it has portions of code that will run outside the security model of the CLR. But then the developer (when he's using unmanaged code) is taking responsibility for what he's doing. He'll have to make sure his native code blocks don't have any gaping holes.

Java won't let you do that - Java is probably meant for babies and little children***(see below). C++ is targetted at tougher people - or rather tougher programmers. What's more, C# and VB.NET can use .NET code access security features to make sure that unmanaged transitions are disallowed.

Uhm.. there is no semantic difference between java bytecode and IL. IL is run in the .NET interpreter, and the java bytecode is run in the java virtual machine. Or have I missed something..? -- My name in Katakana is ヨルゲン. My name in German is Jörgen. I blog too now[^]

There's no such thing as an ".NET interpreter". .NET always executes code natively. The IL gets compiled into x86 instructions by the JITter before executing.

Yeah that's true, but I thought Java also now has a JIT, so I think the argument that they are semantically similar still holds.

On the "Administrative Tools", you have "Microsoft .NET Framework Configuration". There, you can configure everything about .NET security: you have a great granularity and you can even say how the same assembly should execute when invoked from different assemblies or different sources (disk, network, internet, etc). Yes, even I am blogging now!

C++ is targetted at tougher people - or rather tougher programmers. That's a very arrogant statement from you Nish, and it's perfectly wrong: Java lets you shoot yourself in the foot, but in such a subtle way that you have to understand fully the implications of using a garbage collector. Actually, the same pitfalls exists for (managed) .NET solutions. But, at least in C#, you can get some help from the language. Yes, Java was built with syntax simplicity in mind, but you have to be a baby, or a little child, to think that you can make anything usefull without knowing the possible dangers. And that goes for any language and technology. Nishant S wrote: If he wants to make grand statements like that, he could at least have got the facts right. While I agree, that the guy was comparing apples and oranges, I fail to see where he was actually wrong when he calls use of Unmanaged code a security hole. It is a security hole, isn't it? Anyway, it's actually easily comparable to the Java/JNI situation, so he was either just helpfully pointing out the risks, or purposly ignoring the problems in his own camp.

Yeah that's true, but I thought Java also now has a JIT, so I think the argument that they are semantically similar still holds.
I know Java now comes with a JIT too, but the JVM architecture and bytecodes were designed to be interpreted so the have to make several trade-offs to ensure this is possible. On the other hand, .NET was designed from the start to run as native code, using IL as an intermediate step. For these reasons, I don't think that there is a semantic similarity between the JVM and the CLR. Maybe it may help to visualize them as similar, but once you hit the details, there are so many architectural differences that the similarity doesn't hold and just confuses people.
