Rastislav Cesnek commented on SUREFIRE-967:
-------------------------------------------
I see, one of the reasons could be that a JVM can throws "fast exceptions"
(after it optimizes the code execution) which do not have stack trace set.
> ArrayIndexOutOfBounds in SmartStackTraceParser

> Key: SUREFIRE-967
> URL: https://jira.codehaus.org/browse/SUREFIRE-967
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Surefire Plugin
> Affects Versions: 2.13
> Environment: *
> Reporter: Rastislav Cesnek
>
> We are testing using JUnit tests against Webshphere 7 aplication server.
> For some whatever strange reason, WebSphere creates an exception chain, in
> which not all exceptions in the chain have a stack trace array filled in. (I
> have heard rumors of JVMs loosing stack traces in exceptions under some
> strange conditions).
> The result is the following exception in Surefire 2.13 (with 2.11, the tests
> pass and report is generated correctly as the exception processing is
> different from 2.13 as I have seen):
> [INFO] There was an error in the forked process
> org.apache.maven.surefire.testset.TestSetFailedException:
> java.lang.ArrayIndexOutOfBoundsException: 0; nested exception is
