…tation() Production logs show a recurring WARN at startup: "could not get type for name org.conscrypt.AllocatedBuffer" (org.reflections.ReflectionsException / ClassNotFoundException) Root cause: ReflectUtil.getClassesWithAnnotation() uses ClasspathHelper.forPackage() to collect URLs to scan, but this returns all classpath entries (JARs/directories), not just those containing the target package. The Reflections library then scans every .class file in every JAR — including Netty's ConscryptAlpnSslEngine$BufferAdapter which references the optional org.conscrypt.AllocatedBuffer type. During expandSuperTypes(), Reflections tries Class.forName() on that type and fails because Conscrypt is not (and need not be) on the classpath. The fix adds a FilterBuilder that restricts bytecode scanning to only classes whose fully-qualified names match the requested packages. This prevents Reflections from processing unrelated classes (e.g., io.netty.handler.ssl.*), eliminating the warning and reducing startup time by skipping thousands of irrelevant class files.

@vishesh92 a [SL] Jenkins job has been kicked to build packages. It will be bundled with KVM, XenServer and VMware SystemVM templates. I'll keep you posted as I make progress. |

Description
Production logs show a recurring WARN at startup:
"could not get type for name org.conscrypt.AllocatedBuffer"
(org.reflections.ReflectionsException / ClassNotFoundException)
Root cause: ReflectUtil.getClassesWithAnnotation() uses ClasspathHelper.forPackage() to collect URLs to scan, but this returns all classpath entries (JARs/directories), not just those containing the target package. The Reflections library then scans every .class file in every JAR — including Netty's ConscryptAlpnSslEngine$BufferAdapter which references the optional org.conscrypt.AllocatedBuffer type. During expandSuperTypes(), Reflections tries Class.forName() on that type and fails because Conscrypt is not (and need not be) on the classpath.
The fix adds a FilterBuilder that restricts bytecode scanning to only classes whose fully-qualified names match the requested packages. This prevents Reflections from processing unrelated classes (e.g., io.netty.handler.ssl.*), eliminating the warning and reducing startup time by skipping thousands of irrelevant class files.
