Christopher Mosher created SUREFIRE-906:
-------------------------------------------
Summary: Sometimes get NullPointerException in forked process
Key: SUREFIRE-906
URL: https://jira.codehaus.org/browse/SUREFIRE-906
Project: Maven Surefire
Issue Type: Bug
Components: process forking
Affects Versions: 2.13.0
Environment: Arch linux
Reporter: Christopher Mosher
(This is using the latest 2.13-SNAPSHOT)
Using forkMode=perthread, the child processes sometimes abort with this
exception:
java.lang.NullPointerException
at java.io.File.<init>(File.java:251)
at
org.apache.maven.surefire.booter.BooterDeserializer.deserialize(BooterDeserializer.java:61)
at
org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:63)
It only happens sometimes.
Using -X keeps the temp files, and looking at the file that's supposed to pass
the properties, I see that the file is truncated midway, causing the exception.
Possibly the parent process needs to *flush* the file after it writes to it
before is closes it.
