Well, following the advice in the thread "Re: java/jdk15 build failure on amd64", I finally managed to build and install jdk-1.5.0 on my amd64-current box. Unfortunately, preliminary results are extremely disappointing.
It seems that any java app I try running instantly tries to allocate an entire gigabyte of RAM right off the bat. Running apps are showing sizes of 1200, 1300, 1400 megs, which is just completely crazy. The same apps running with jdk-1.5.0 on my 32-bit Athlon box under STABLE are fine, no such craziness with memory allocation.
Is anyone else seeing the same sort of thing? Right now, for me, jdk-1.5.0 is all but useless on my amd64 box (I only have 512 megs of physical RAM; but even if I had more, this sort of memory hogging is just completely out of line). :-(
I quickly tried some apps from ports (finance/venice editors/jedit) and they seem to function without obvious problems. I have 1 GB memory. Venice uses 2.5 MB on my i386 box and 4.8 MB on the amd64 box (both with jdk15). Jedit seemed equally bigger on amd64. Maybe that shouldn't be a surprise with a 64 bit architecture. Thinking back on it, though, I did recompile jdk15 using jdk15 instead of the linux-sun-jdk bootstrap. Don't know if that matters.
