---------------------------------------
Resolution: Duplicate
> ReporterManager causes OutOfMemoryException
> -------------------------------------------
>
> Key: SUREFIRE-581
> URL: http://jira.codehaus.org/browse/SUREFIRE-581
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Surefire Plugin
> Affects Versions: 2.4.3
> Environment: Linux,JDK 1.6.0.07, surefire 2.4.2
> OSX, JSK 1.5/1.5, surefire 2.4.2, 2.4.3
> Reporter: Emilian Bold
> Priority: Critical
>
> I have some unit tests that indirectly generate a lot of output to stdout/stderr. What I have been noticing on the build server is that a lot of these tests die with OutOfMemory errors.
> After profiling the testcase locally, it seems the cause isn't my own code, but the Maven runtime.
> Specifically, the org.apache.maven.surefire.report.ReporterManager class seems to like holding the entire output *in RAM* via the variables:
> private ByteArrayOutputStream stdOut;
> private ByteArrayOutputStream stdErr;
> The actual contents of these seem to be disregarded unless the test is failed, at which point you need the entire string, again, in RAM.
> I wanted to provide a patch for this but I couldn't find a nice one as the design is a big unfortunate: org.apache.maven.surefire.report.Reporter expects a String for stdout/stderr -- perhaps a CharSequence would be nicer and we could have an adapter over a temporary file insted of a ByteArrayOutputStream.
