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.
