Linux Wine Java max heap size, -Xmx

jra · Post by **jra** » Thu Nov 01, 2012 6:47 pm

Java max heap size, -Xmx, seems to be drastically limited when running under Wine on Linux.

A couple of examples:

RHEL 6.3, wine 1.4.1, Java 6, 12GB
largest accepted: -Xmx320m

Ubuntu 11.04, wine 1.2.2, Java6, 32G
largest accepted: -Xmx1152m

Is there a way to get larger max heap sizes for Java under Wine?

Why is it so limited?

(unfortunately, running Java directly under Linux is not an option)
