I am getting a NullPointerException from
PersistenceUnitInfoImpl$PersistenceClassFileTransformer.transform() when
running in Java 8.
I have a command line application using openejb-core-4.7.2 and running in
Java 8, so when starting the app it runs using the javaagent
openejb-javaagent.jar.
This app uses JPA, but also has some legacy code that gets jdbc connections
using a BasicDataSource.
Now whenever it gets a jdbc connection the javaagent seems to be doing some
manipulations of the byte code and a NullPointerException is thrown from
org.apache.openejb.persistence.PersistenceUnitInfoImpl from the method
PersistenceClassFileTransformer.transform at the line that reads 'String
replace = className.replace('/', '.');'. So className appears to be null.
This is the method where the exception comes from
public byte[] transform(ClassLoader classLoader, String className, Class<?>
classBeingRedefined, ProtectionDomain protectionDomain, byte[]
classfileBuffer) throws IllegalClassFormatException {
String replace = className.replace('/', '.');
return
PersistenceUnitInfoImpl.isServerClass(replace)?classfileBuffer:this.classTransformer.transform(classLoader,
replace, classBeingRedefined, protectionDomain, classfileBuffer);
}
When running this same app in Java 7 no exceptions are thrown.
This is the stack trace:
