[news.eclipse.tools.hyades] Re: Problem loading classes from external ja

[lubosp@xxxxxxxxx (Lubos Pochman)]

Thanks Curt for responding.

As highlighted in the bug it looks like the problems is compatibility with 
Eclipse 3.1.
I have tried to run it as an external program, it runs and I can attach to 
it, but it requires so many resources (both CPU and memory), that evan my 
Pentium 4 3Gz with 512Mb of memory cannot handle it, and eventually the 
profiled application crashes (out of resources?).
So I think it is time for me to remove Hyades from my system and wait when 
it is more stable and part of the Eclipse IDE (or somebody writes JFluid 
plugin ;-).

Thanks, Lubos
