ant with java 6 update 6 is slow

[denisbytezone]

I'm using Eclipse 3.3.2 with java 6 update 6. Suddenly a trivial
compile takes 14 seconds, when before it took 1 second.

I can change my Eclipse jre from update 6 to update 5 and back, and
whenever I use update 5, the compile time goes back to 1 second.

Anyone know what is causing this?

When you use ANT impendent of Eclipse, how does it behave?

Is your JAVA_HOME and Path set correctly?

That's all handled internally by Eclipse. To prove it, I can set my
JRE (inside Eclipse) to update 4, 5 or 6. Compile times are normal
when just using Eclipse, but when using ANT compile takes 1 second
(U4), 1 second (U5), 14 seconds (U6). If it was a path problem, 2 out
of 3 would be slow.

I never use ANT outside Eclipse.

There is a difference between choosing JREs and choosing source and
object target levels. Do you actually have all three JRE's installed?

It seems to me you should be selecting JDKs not JREs in any case,
since you want to change the Java compiler not just the Java than runs
ANT.

I use ANT outside of Eclipse, with JDK 1.0.6_06. I don't experience
any slowdown.

This is why I think the problem is with Eclipse not Ant/Java.

That is why I think it would help to narrow down the problem by
running your ANT script outside of Eclipse.

I'm seeing the same problem, and we are using Ant without Eclipse.

Has there been any update on your problem?
