java.io.IOException: Could not start process: <EOF>

I’m only seeing this error on our CI machine, a SLES 10.2 box (kernel version 2.6.16.60-0.21-smp). I get the error both running through Jenkins and from a workspace I cloned on that machine to try to debug. The same code runs fine on my Mac, my co-workers Mac, and elsewhere on a OLE 6.3.1 box (kernel version 2.6.32-279.11.1.el6.x86_64). Here’s the exception:

This is a Spring Boot application, that makes heavy use of auto-configuration, but I’m specifying the IRuntimeConfig like so, because I need to provide the proxy info:

@Primary
@Bean
IRuntimeConfig runtimeConfig()
{
    final Command command = Command.MongoD;
    return new RuntimeConfigBuilder()
        .defaults(command)
        .artifactStore(new ExtractedArtifactStoreBuilder()
                           .defaults(command)
                           .download(new DownloadConfigBuilder()
                                         .defaultsForCommand(command)
                                         .proxyFactory(new HttpProxyFactory("proxy.employer.com", 80))
                                         .build()))
        .build();
}

I’ve tried the workaround mentioned on another ticket of setting LC_ALL=C, to no avail. Let me know if there’s any additional information I should gather.

I figured it out. The following worked for me in my Dockerfile:

WORKDIR /build-env
ADD . /build-env
RUN apk update &&  apk add bash && apk add libstdc++
ENV LC_ALL=C
RUN ./gradlew build```

This problem happens only if your environment is configured to run on 32bit java. Try running with 64bit java and the issue should disappear. Short explanations is that during mongod initialization, based on the java platform, the embedded-mongo will decide which mongod build to use. For the 32bit monogod build, the default “wiredTiger” storage engine is not available and the process could not start.
