Look at

        linux_i386-JDK-1.4.0-beta_refresh.20010621.1725.1

and compare it to the other 

        linux_i386-JDK-1.4.0-beta_refresh.20010621.1725.*

files in that directory.  (Not any that may still be in 
progress when you get there.)  That one says

in the middle of what looks like a perfectly good run.  
The runs on win32_i486 and solsparc don't seem to do that.  
The other linux_i386 runs don't seem to do that.  Is it 
something we should worry about, or just put it down to 
randomness?  

Everything I know about the bug is in that directory or the 
corresponding bug report.  The source code is in there.  It 
used to throw OutOfMemoryError, but we seem to have fixed that.  
It's no where near running out of memory at the point it gets 
that exception. The difference between LoadTest.java and 
LoadTest_pbk is that I took out an annoying "\r" from the 
output at line 574.
