Druid doesn't build with OpenJDK (on Ubuntu 12.04) about druid HOT 7 CLOSED

What error do you get? Would be nice if it built.

from druid.

@octavore may have some feedback for you. It was a fresh VM and there may have been issues with the maven version, we're not sure.

from druid.

I had issues as well, switching to the sun (oracle) jdk fixed it.. I seem to recall finding where I think the issue might be fixed in openjdk but not yet trickled into the packaged version in ubuntu..
$ java -version
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-0ubuntu1~12.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

Here's a snippet from build.sh output where it fails:

I got it to build as follows on Ubuntu 12.04, by installing OpenJDK7 and pointing my JAVA_HOME to it:

sudo apt-get install openjdk-7-jdk maven
JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/ ./build.sh

It's related to these:

I just pushed a fix that I think will work around this issue. If it doesn't, well, the code still works as is and has a lot more spots where it's specifying generics, but oh well ;).

Not working...

Ok, actually read the links jeremybarnes posted and I think that removing the Maps.newTreeMap() calls and just using the plain old "new TreeMap<>()" invocation will fix the problem. Pushed a fix, hopefully it works.
