Subject RE: javac Task Using Jikes with Large Number of Files
Date Fri, 14 Jul 2000 01:20:47 GMT
There is an issue (on my todo list) about sending too many compile files to
Jikes since it seems to overflow the capabilities of the Runtime.exec
system. The limit is something like 300 or 380, I can't remember exactly and
its probably system dependent. Try breaking your compile into smaller
bundles.
