Unable to run 32 bit eclipse on 64 bit machine

[Arun Hiremath]

I need to run a 32 bit eclipse on my 64 bit workstation as I have a plugin which works only on 32 bit eclipse.

When I try to do so, I get the following stack trace:
 ./eclipse -consoleLog

Additional Info:
I have both the 32 bit and 64bit JDK installed o n my machine.

I will try to un-install both and then just install the 32 bit one.. I am afraid that this might degrade overall system performance and might not even work.

Does anyone know of any working solution??

This may not be a bug per se.

I just need to know the steps to proceed in this scenario.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in eclipse.

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Hi

You will need to run eclipse in/with a 32 bit JVM to accomplish this (see eclipse's -vm argument). I am not sure whether it is possible to install a 32 bit JVM on a 64 bit system with APT currently though.
