preferring java-gcj causes erratic workspace configuration setting

[brettatoms]

If $JAVA_HOME is set then eclipse will use...
$HOME/.eclipse/org.eclipse.platform_3.1.2/configuration/.settings$ less org.eclipse.ui.ide.prefs
...for its custom user settings.

If $JAVA_HOME is not set then eclipse will run using java-gcj. If ~/.eclipse is deleted then the prefs file mentioned above is never even created and I can't figure out how to change the default location of the workspace from ~/workspace.

If you hava JAVA_HOME set in ~/.bashrc then running eclipse from the terminal and from deskbar-applet can give you different workspaces.

oops, bad paste. configuration file should be....
$HOME/.eclipse/org.eclipse.platform_3.1.2/configuration/.settings/org.eclipse.ui.ide.prefs

Just a question (my report on bug #36354 is possibly in a way related to your bug): What is your $JAVA_HOME setting? Do you have thze same problem when calling eclipse with the -vm command line option?

I assume you mean #36534 not #36354 (Canon S400 and S100 printing
problem) ;)

$ echo $JAVA_HOME
/usr/lib/j2sdk1.5-sun

$ eclipse -vm /usr/lib/jvm/java-gcj/jre/bin/java

Running with the -vm option as above doesn't seem to use the same
configuration configuration setting as when using the vm from
$JAVA_HOME.

$ eclipse -vm /usr/lib/j2sdk1.5-sun/jre/bin/java
Uses the proper configuration.

Moreover, using Eclipse 3.2.2 on Hardy (Build id: M20070212-1330 (Ubuntu version: 3.2.2-5ubuntu2)), Eclipse use by default the GCJ JVM and doesn't ask for workspace whatever the value of SHOW_WORKSPACE_SELECTION_DIALOG in ~/.eclipse/org.eclipse.platform_3.2.0/configuration/.settings/org.eclipse.ui.ide.prefs. It's an obvious bug due to the GCJ JVM because it doesn't appear with the Sun JVM.

Globally, I think that the default order of the preferred JVM in the file /etc/eclipse/java_home is not the better choice. I already have problems with Eclipse 3.0 which was very slow with the gcj version. Now, I got this problem with workspace location dialog which doesn't appear. I personally think that the order hereunder must be the default one (with gcj and kaffe at the end) :

#/usr/lib/jvm/java-7-icedtea
/usr/lib/jvm/java-6-sun
/usr/lib/jvm/java-1.5.0-sun
/usr/lib/j2se/1.5
/usr/lib/j2se/1.4
/usr/lib/j2sdk1.5-ibm
/usr/lib/j2sdk1.4-ibm
/usr/lib/j2sdk1.6-sun
/usr/lib/j2sdk1.5-sun
/usr/lib/j2sdk1.4-sun
/usr/lib/jvm/java-gcj
/usr/lib/kaffe/pthreads

Hi

We no longer have a predefined list of "preferred" JVMs for eclipse (since 3.5.1). While the documentation has not been updated to reflect this, we also now ignore $JAVA_HOME[1], $JAVA_CMD[1] and ~/.eclipse/eclipserc.
