There seems to be some system specific factors that determine the max
memory value. I found that on my system (WinXP SP2, 2.5 GB RAM, virtual
memory 768M-3G, imagej 1.37q), I can only set the -Xmx value up to 1468m.
Anything more than that will cause the error "could not create the Java
virtual machine" by Java Virtual Machine Launcher. Here is my start
script
"C:\Program Files\Java\jre1.5.0_06\bin\javaw.exe" -mx1468m -cp
ij.jar;jimi.jar;C:\windows\System32\QTJava.zip ij.ImageJ
Trial and error is how I get to that value. By the way, running the
script on the commandline did not yield anymore information about
unrecognized option. Am I missing anything here?
