Question

I have installed Eclipse on Debian Lenny after having installed java (apt-get install sun-java6-jre sun-java6-plugin sun-java6-jdk).

When I run Eclipse, I have the following message when it comes to selet the folder that will be used as the workspace:

GCJ has been detected as the current Java virtual machine.
Use of GCJ is untested and unsupported.
Please consult the documentation for more

I just ignored this message and go into "help" -> "software updates" to install android development tools. When I add "https://dl-ssl.google.com/android/eclipse/" to download the Developer tools, I got an error (see below) and the installation cannot go any further. Is that due to the Garbage Collector message I got above ?

Below are the error I got on the console from which I run eclipse:

lj:/home/luc# eclipse/eclipse
GC Warning: Out of Memory!  Returning NIL!
GC Warning: Out of Memory!  Returning NIL!
GC Warning: Out of Memory!  Returning NIL!
GC Warning: Out of Memory!  Returning NIL!

Error while logging event loop exception:

Logging exception:

....

Thanks a lot for your help, Luc

This message is your clue:

GCJ has been detected as the current Java virtual machine.

That means your system Java is still the GCJ version, not the Sun version.

If you don t need GCJ for other things, you can remove the package (apt-get remove or apt-get purge). This might break other dependencies though.

Otherwise, use update-alternatives to configure which package supplies your java and javac commands:

update-alternatives --config java
update-alternatives --config javac
