jdk 1.3.0 / sparc
Hi All, Hope all is well. We've just noticed that the Blackdown JDK 1.3.0 for sparc is available and have installed it on our E250 system. Great work, but I wanted to ask what performance expectations we should have ? Our tests have shown that the Blackdown sparc JDK 1.2.2 is faster than the JDK 1.3.0 ? Could this be right ? A compile of our Java application using JDK 1.2.2 takes about 1 minute, with the JDK 1.3.0 it takes about 4 minutes. :-( Is this expected ? Any ideas about how to improve this ?

Take a look at ANT from the Apache Java Project. We're using it with
great success here. I highly recommend it.

I see. Thanks for the information.

*nod*. I can understand the move to 1.4.
wrt your last question, I have to ask first - is there a proposed
timeline for the 1.4 releases at all ? How soon will it be before we
get our hands on a (beta?) version ?
How much effort do you think it would it take to get 1.3.0/1 up to
speed ?
Cheers,
Marcus

It's really great to hear this, especially the support for hotspot.
We're really looking forward to using it.
Thanks to the team for the ongoing effort to support sparc linux as a
java platform.
Cheers,
