Netbeans code completion screwed up

Question

Something has gotten horribly screwed up in my netbeans configuration, and I cannot figure out what it is or how to fix it. I'm running netbeans 8.0 c++ on debian 7.4. When I have this code:

#include <cstdlib>
#include <vector>

using namespace std;

int main(int argc, char** argv)
{
    vector<int> h;
    h.push_back(4); //THIS LINE
    return 0;
}

Netbeans underlines the line I have a comment on in red and says it's unable to resolve identifier push_back. When I just type h. the suggestions come up with a bunch of vector constructors, but no methods like push_back or erase. I can't understand why that is, it was working an hour ago and I haven't changed anything since. It broke when I opened one of my projects.

I've tried opening and closing the project, closing and opening netbeans, rebooting my computer, and reinstalling netbeans. Nothing worked.

Solution found : OpenJDK 7 is buggy.

To solve this problem I installed Oracle JDK 1.7 in my home directory, and I removed three directories ~/.cache/netbeans, ~/.netbeans and ~/.nbi. I updated the netbeans_jdkhome variable in the file ~/netbeans-dev-201405050001/etc/netbeans.conf to the path of Oracle JDK 1.7.

Now the C++ Netbeans parser works perfectly, whatever the complexity of statements.
