Invalid initial heap size: -XmsM

Submitted by Claribob on Saturday, 5 September, 2009 - 14:10

Hi ! My OS is Fedora 10. I'd like to get Jedit up and running so I can use the Lilypond plugin. So, I followed instructions at the Lilypondtool web site: http://lilypondtool.organum.hu/86.html It told me to install Java Runtime 5.0 and gave instructions which I followed. Then to get Jedit 4.3pre16 or later. I downloaded 4.3pre17 It took me hours to finally get Java installed, I think. When I give this command in terminal: update-alternatives --config java I get a listing which shows three java files. The Plus (+) symbol is on jre1.6.0_16 and when I give this command in terminal: java -version it also lists jre1.6.0_16 This is what's it's supposed to be for Lilypondtool. Then I installed Jedit4.3pre17install.

But, when I try to run Jedit from terminal, I get the following: Invalid initial heap size: -XmsM Could not create the Java virtual machine. Anyone using Jedit in Fedora who can help me with this ?

You have to check the command line witch is used to start jEdit. This depends on how You invoke jEdit. The command line options for memory control look like: -Xms64M -Xmx192M. Apparently the number inside the argument is missing for You.

The jEdit home directory should contain a shell script. Maybe this is used but not valid. Take a look into it and try...

Here's the contents of what may be the shell script to start Jedit:
Can you look at this, Robert, and suggest what to do next ?

#!/bin/sh
#
# Runs jEdit - Programmer's Text Editor.
#

# Set jvm heap initial and maximum sizes (in megabytes).
JAVA_HEAP_MAX_SIZE=192

DEFAULT_JAVA_HOME="/opt/java/jre1.6.0_16"
if [ -z "$JAVA_HOME" ]; then
JAVA_HOME="$DEFAULT_JAVA_HOME"
fi

# Launch application.

exec "$JAVA_HOME/bin/java" -Xms${JAVA_HEAP_INIT_SIZE}M -Xmx${JAVA_HEAP_MAX_SIZE}M -jar "/usr/local/share/jedit/4.3pre17/jedit.jar" "$@"

I'm not familiar with *nix. But this script cannot work. Has it been created by the installer?

You should insert this new line:
JAVA_HEAP_INIT_SIZE=64

before this existing line:
JAVA_HEAP_MAX_SIZE=192

I guess it was created by the installer. I've tried to add that line using gedit. Never did this before (only using Fedora a few months now). Gedit won't let me save the file. I don't have permission. I started gedit from the GUI. RL

Ok, I was able to edit the Jedit shell file to add that line. Jedit opens up now. Thanks ! Robert. For any nubbie to Fedora, I logged in as root, navigated to the directory for the Jedit shell file, and typed gedit jedit. Added the line, saved it and Jedit started up normally by simply typing jedit

This bug in the installer should be fixed in the next jEdit version.
