Re: [hibernate-dev] WildFly tests with ByteBuddy enhancement are failing
Hi Gail,
Do we have any idea of what this class is supposed to be:
org.jboss.as.test.integration.jpa.basic.SLSBPersistenceContexts$$$view5 ?
Scott, any idea?
Because it doesn't ring a bell on my side.
I suspect it's a class we shouldn't access or touch. And we should probably
add a condition somewhere to avoid doing so.
If you can give me the Hibernate call which initiates the error, that would
be nice.
And stupid question: we did not have any enhancement test in WildFly before
that?

Scott added bytecode enhancement to some WildFly tests for WFLY-11891

Here is Scott's PR with the updated tests: [2]
When I stepped into
org.jboss.as.test.integration.jpa.basic.multiplepersistenceunittest.MultiplePuTestCase,
I can see that they are failing in ByteBuddy code.
I see that:
- enhancement of
org.jboss.as.test.integration.jpa.basic.SLSBPersistenceContexts gets
skipped several times in a row;
- enhancement of some other classes get skipped;
- before trying to enhance
org.jboss.as.test.integration.jpa.basic.SLSBPersistenceContexts$$$view5, an
exception is thrown.
Unfortunately, I'm having trouble getting a good stacktrace to show what
happens in ByteBuddy code.
Here is what I'm seeing:
net.bytebuddy.pool.TypePool$Default.doDescribe("org.jboss.as.test.integration.jpa.basic.SLSBPersistenceContexts$$$view5")
/* class name differs from run to run */
calls net.bytebuddy.dynamic.ClassFileLocator$ForClassLoader.locate( "
org.jboss.as.test.integration.jpa.basic.SLSBPersistenceContexts$$$view5")
calls net.bytebuddy.dynamic.ClassFileLocator.ForClassLoader.locate(
classLoader,
"org.jboss.as.test.integration.jpa.basic.SLSBPersistenceContexts$$$view5"
)
calls
classLoader.getResourceAsStream("org/jboss/as/test/integration/jpa/basic/SLSBPersistenceContexts$$$view5.class"),
which returns null;
(I don't actually see a class file with this name)
returns new TypePool.Resolution.Illegal(
"org/jboss/as/test/integration/jpa/basic/SLSBPersistenceContexts$$$view5.class"
)
returns TypePool.Resolution.Illegal
Ultimately, TypePool.Resolution.Illegal#resolve( ) throws
IllegalStateException, because the type description cannot be resolved.
I'm not sure if the problem is in WildFly, Hibernate, or ByteBuddy.
To build WildFly:
./build.sh clean install -DskipTests=true
To run the test:
cd testsuite/integration/basic
mvn install
-Dtest=org/jboss/as/test/integration/jpa/basic/multiplepersistenceunittest/MultiplePuTestCase
Help would be very much appreciated.
Thanks,
Gail
