Alexander Ashitkin commented on SUREFIRE-1132:
----------------------------------------------
I was able to log classloader config and provider properties at the moment of
failure. As i understan junit.jar was not present in the classloader:
{code}
13:40:42 Classloader: sun.misc.Launcher$AppClassLoader@5c647e05 parent:
sun.misc.Launcher$ExtClassLoader@3e3abc88

f:true d:false r:true
{code}
The data is captured as follows:
{code}
public static SurefireProvider createProviderInCurrentClassloader(
StartupConfiguration startupConfiguration1,
boolean
isInsideFork,
ProviderConfiguration providerConfiguration,
Object
reporterManagerFactory1 )
{
BaseProviderFactory bpf = new BaseProviderFactory( (ReporterFactory)
reporterManagerFactory1, isInsideFork );
bpf.setTestRequest( providerConfiguration.getTestSuiteDefinition() );
bpf.setReporterConfiguration(
providerConfiguration.getReporterConfiguration() );
ClassLoader clasLoader = Thread.currentThread().getContextClassLoader();
bpf.setClassLoaders( clasLoader );
bpf.setTestArtifactInfo( providerConfiguration.getTestArtifact() );
bpf.setProviderProperties(
providerConfiguration.getProviderProperties() );
bpf.setRunOrderParameters(
providerConfiguration.getRunOrderParameters() );
bpf.setDirectoryScannerParameters(
providerConfiguration.getDirScannerParams() );
int reattempts = 0;
while ( reattempts < 3 )
{
try
{
return ( SurefireProvider ) ReflectionUtils.instantiateOneArg(
clasLoader,
startupConfiguration1.getActualClassName(),
ProviderParameters.class, bpf );
}
catch ( Throwable e )
{
reattempts++;
System.err.println( Thread.currentThread().getName()
+ ": Error creating provider with configuration: " +
providerConfiguration );
e.printStackTrace();
System.err.println( "Classloader: " + clasLoader + " parent: "
+ clasLoader.getParent() );
if ( clasLoader instanceof URLClassLoader )
{
final URLClassLoader ucl = (URLClassLoader) clasLoader;
final URL[] urls = ucl.getURLs();
for ( URL url : urls )
{
try
{
final URI uri = url.toURI();
final File file = new File( uri );
if ( file.exists() )
{
System.err.println( url + "f:" + file.isFile()
+ " d:" + file.isDirectory() + " r:" +
file.canRead() );
}
}
catch ( URISyntaxException e1 )
{
System.err.println( "Error converting url: " + url
);
e1.printStackTrace();
}
}
}
try
{
System.err.println( "Sleeping before reattempt" );
Thread.sleep( MILLIS );
}
catch ( InterruptedException e1 )
{
e1.printStackTrace();
Thread.currentThread().interrupt();
}
}
}
throw new RuntimeException( "Failed to create provider" );
}
{code}
thats all i see. No artifact dependencies, only compiled code and surefire apis
in classpaths. Is it something expected and i need to look something else?
thank you
> Surefire: regular isolated classloader failures in parallelbuild

> Key: SUREFIRE-1132
> URL: https://jira.codehaus.org/browse/SUREFIRE-1132
> Project: Maven Surefire
> Issue Type: Bug
> Components: classloading
> Affects Versions: 2.17, 2.18.1
> Environment: SLES 3.0.80-0.7-default SMP x86_64 GNU/Linux
> windows server 2008 x64
> Maven 3.2.2, 3.2.3, 3.2.5

>
> We have a large project of 300+ modules which regularly fails with different
> kind of classloading issues in different places in surefire plugin. The issue
> is reproduced only with parallel build and is not reproduced in single
> threaded. This is a main contributor in build instability for us. All the not
> loaded dependnecies are actually present in dependency tree. I attached 3
> different samples of how build fails.
> Surefire config:
> {code}
> <configuration>
> <forkCount>0</forkCount>
> <!--doesnt work in parrallel build. Causes build
> failures with error java.io.IOException: Stream Closed-->
> <redirectTestOutputToFile>false</redirectTestOutputToFile>
> <useManifestOnlyJar>false</useManifestOnlyJar>
> </configuration>
> {code}
> maven cmd is like install -T 10
> Please advise how to sort this out - ready to run any provided diagnostic
> and evaluate any options.
> Thanks in advance, Alexander
