AFAICT yes, it is possible that 1Gb (try 2Gb to be sure) swap
will solve it. I can start trying to imagine how long it would take
to compile jdk15, though. And even if you do succeed, an
average java application can take about 100Mb of RAM
right from the start. So you should really choose between a
newer box and a sensible programming language.
