JDK5 for 64 bits?

Hey there,

I have been looking for the JDK 5 for 64 bits, at this point I have found a version for amd64 architecture but nothing for x64. I am wondering if there is support of Java 5 for x64 architecture.

I already checked the Oracle Java Archive web page ( without success.

Could you please help me to confirm that, indeed, there is no support of Java 5 for x64 architectures? I will really appreciate your help.

PD. I know that Java 6 and earlier supports it, but not sure about Java 5.

Thanks in advance!

amd64 and x64 is the same. You can use the amd64 on an Intel processor as well as on an AMD processor; there's no difference.

AMD, not Intel, first invented 64-bit instructions for Intels x86 processor architecture, and therefore sometimes it is called "amd64". Intel later implemented AMD's 64-bit instructions in their processors and called it "x64".

Note that there's also IA64, which is different. This is for Intel Itanium processors, which are very different from Intel x86 processors that you find in normal PCs.

Thanks Jesper!

I installed the JDK5 amd64 distribution on my Intel processor and it works. As you said, it looks like amd64 and x64 are just two names to refer the same architecture.
I agree. Here's the link:
