[jira] (SUREFIRE-843) Unable to run 'mvn test' with Java 7
Niraj Tolia created SUREFIRE-843:
------------------------------------
Summary: Unable to run 'mvn test' with Java 7
Key: SUREFIRE-843
URL: https://jira.codehaus.org/browse/SUREFIRE-843
Project: Maven Surefire
Issue Type: Bug
Components: Maven Surefire Plugin
Affects Versions: 2.12
Environment: Mac OS X
java version "1.7.0_04-ea"
Java(TM) SE Runtime Environment (build 1.7.0_04-ea-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b15, mixed mode)
Reporter: Niraj Tolia
I am trying to run mvn test and it always fails at some arbitrary time with the message 'Error occurred in starting fork'. See the output below. Note that it does not execute all tests but fails in between the test run. The number of tests surefire finishes executing is random but it has never completed the entire test run. I am using Java7u4 Build b13 with Maven 3.0.3 and surefire v2.12.
Any clue what might be going wrong? This is a blocker for me.

[jira] (SUREFIRE-843) Unable to run 'mvn test' with Java 7
Posted by "Niraj Tolia (JIRA)" <ji...@codehaus.org>.

Niraj Tolia commented on SUREFIRE-843:
--------------------------------------
Sneha: Try these steps to narrow down your problem:
1. Configure surefire to fork unit tests and then run mvn -X test.
2. Grab the surefire startup line from the debug output (should start with /bin/bash).
3. Execute that command directly and when it fails, run 'echo $?' to get the status.
4. Then grep all your code or any external code that might be calling System.exit() with that status.

[jira] (SUREFIRE-843) Unable to run 'mvn test' with Java 7
Posted by "Niraj Tolia (JIRA)" <ji...@codehaus.org>.
[ https://jira.codehaus.org/browse/SUREFIRE-843?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Niraj Tolia closed SUREFIRE-843.
--------------------------------
Resolution: Not A Bug
Turned out the problem was with an external library that was calling System.exit(). This seems to be a timing problem that has never been triggered by Java 6 (hundreds of 'mvn test' runs) but reliably occurs with Java 7.
