Xmx > 1024 := Could not create the Java virtual machine

[Oliver Baum]

Hi

Since yesterday I have problems with eclipse start.
Normaly I start eclipse with a batch file with follow command:

start /D%PRJ_HOME%\tools %ECL_HOME%\eclipse -vm %JAVA_HOME%\jre\bin\javaw -data %WSP_HOME% -vmargs -Xms 512m -Xmx 1536m -XX:MaxPermSize=128M

Since yesterday I cannot start eclipse with the parameter Xmx 1536m. It works only when I use Xmx 1024m.

Yesterday they installed a few Microsoft Security Patches. I deinstalled all, but it still dosn't work. Have somebody an idea?


I use jdk1.5.0_16.

Thanks for help

I've had the same problem using non-1024m multiples.

I'm not sure if this will help, but I found this on java.sun.com. It says that the memory arg has to be a multiple of 1kb i.e. 1024 greater than 2MB.

No change in the more recent version of the java tool documentation. Don't know whether there is any difference for Eclipse, rather than the command-line tool.
