> Surefire plugin does not report fatal VM creation failure
> ---------------------------------------------------------
>
> Key: SUREFIRE-735
> URL: http://jira.codehaus.org/browse/SUREFIRE-735
> Project: Maven Surefire
> Issue Type: Bug
> Reporter: James Phillpotts
>
> Background:
> In a large project with a lot of test classes and classes under test, memory
> settings have been tuned to prevent test failure. However, Java is fussy
> about some memory settings, and if it cannot allocate the amount of memory
> needed, the VM will fail to start.
> Problem:
> When surefire encounters this failure to start, the problem is reported to
> the user as follows:
> {noformat}
> [INFO]
> ------------------------------------------------------------------------
> [ERROR] BUILD FAILURE
> [INFO]
> ------------------------------------------------------------------------
> [INFO] There are test failures.
> Please refer to [snip]\target\surefire-reports for the individual test
> results.
> {noformat}
> The surefire-reports directory does not exist within target.
> Using debug mode, the command that is executed is found, and when run from a
> command prompt window, the following output is received:
> {noformat}
> Error occurred during initialization of VM
> Could not reserve enough space for object heap
> Could not create the Java virtual machine.
> {noformat}
> Obviously there is nothing surefire can do about the failure to start the VM,
> but the error output from the VM itself should be passed back to the user, so
> that they can do something to remedy it.
> I'd supply some steps to reproduce it, but as it would depend on the memory
> available on the machine used to test it, they wouldn't necessarily work, but
> by playing with the Xmx and Xms settings, it should be possible to duplicate
> this.
