  • 0

When I try to use any javascript template Eclipse always hangs and I get this message:
“Unhandled event loop exception Java heap space” on a popup.

I started a top command (using Ubuntu) for the Eclipse process and for Java process and then tried to use an auto-complete on Eclipse. I notice that the Java process takes my CPU to 100% while memory stays the same(arround 22%).

I got this without any prior changes to my Eclipse IDE…

Any ideas on how to solve this?

EDIT:
I notice also that on the preferences window under:
Javascript / Content Assist / Advanced
the option “Other Javascript Proposals” is checked. When unchecked, the problem is solved. However, it lacks the content assist for variables and objects. So this partially solves my problem.

    I managed to find the problem. I temporarily moved some js files to my project (some of them duplicated the original ones) and auto-complete was searching in too many files. So I changed the src folder like this:

    • Right click on project
    • Choose properties
    • Javascript
    • Include path
    • On the source tab I excluded the files/folders that were duplicated and some that I didn’t want to use on auto-complete.

    This solved my problem and my Eclipse is fast now on auto-complete.
