[news.eclipse.tools.hyades] Re: Number of Collected items are 0

["LO" <lars@xxxxxxxxxxxxxx>]

Hi,

Hyades 3.0.0

I'm running the RAC server on Solaris 8
Eclipse IDE is running on Windows 2000
Both are using Sun JDK 1.4.2_03

Perhaps I should upgrade to a newer Hyades (Both Eclipse plug-in and RAC
server) before you start performing some more investigations?
(or switch to the newer 1.4.2_06 JVM)

I'm note sure what to expect when I press the run GC button (long time since
I looked into the JVMPI specs) but will the JVM actaully perform
the GC or will it simply take it to consideration.
