[jboss-user] [JBoss Microcontainer Development] - Duplicate classloading with Javassist Reflect

Ales Justin [http://community.jboss.org/people/alesj] created the discussion "Duplicate classloading with Javassist Reflect" To view the discussion, visit: http://community.jboss.org/message/538334#538334 -------------------------------------------------------------- I'm getting this unexpected behavior while testing my Scanning lib. org.jboss.reflect.spi.CannotCompileException: javassist.CannotCompileException: by java.lang.LinkageError: loader (instance of  org/jboss/classloader/spi/base/BaseClassLoader): attempted  duplicate class definition for name: "org/jboss/test/scanning/annotations/support/FilteredAnnotationScanningPluginFactory"     at org.jboss.reflect.plugins.javassist.JavassistUtil.ctClassToClass(JavassistUtil.java:56)     at org.jboss.reflect.plugins.javassist.JavassistTypeInfo.getType(JavassistTypeInfo.java:195)     at org.jboss.metadata.spi.signature.Signature.convertParameterTypes(Signature.java:151)     at org.jboss.metadata.spi.signature.ConstructorSignature.<init>(ConstructorSignature.java:77)     at org.jboss.metadata.spi.signature.Signature.getSignature(Signature.java:121)     at org.jboss.scanning.plugins.visitor.ClassHierarchyResourceVisitor.handleAnnotations(ClassHierarchyResourceVisitor.java:200) I think this should not happen, since there should be only one instance of matching TypeInfo/ClassInfo. But it looks like we're missing a check if the CtClass is already loaded by the underlying classloader inside that TI/CI instance. Or some other mechanism that would prevent it from getting this duplicate behavior. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538334#538334] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
