Der-Joscha opened a new issue, #2882: URL: https://github.com/apache/drill/issues/2882
Hello, I am currently working on an application with java 21 that uses the jdbc driver from drill to execute distributed sql queries. Since the module system was introduced with Java 9, we get exceptions on startup that drill cannot patch various dependencies (see stacktrace below). I am aware that drill tries to access classes that are not exported via reflection, which fails for obvious reasons. What I already did: - See if there are versions that supprot java>8. I found docker images that use java 17, but I have not found a jdbc driver that supports this version - Add `--add-opens java.base/java.lang=ALL-UNNAMED` to the jvm at runtime, which resolves the issue but is rather unappealing workaround as some drill images seem to support java>8 Our setup is the following: - We are using java 21 and unfortunately cannot downgrade to java 8 due to other dependencies. - We are using maven as a build system and have `org.apache.drill.exec:drill-jdbc:jar:1.21.0` as a dependency Is there a possibility to use the drill jdbc driver with a java version > 8, or are we stuck with our workaround? I will happily provide more information if needed. Thanks in advance. <details> <summary>Stacktrace</summary> org.apache.drill.common.util.ProtobufPatcher patchByteString 2024-02-26T12:45:13.072736994Z WARNING: Unable to patch Protobuf. 2024-02-26T12:45:13.072742894Z java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @edc0eb6 2024-02-26T12:45:13.072747295Z at java.base/java.lang.reflect.AccessibleObject.throwInaccessibleObjectException(AccessibleObject.java:391) 2024-02-26T12:45:13.072750695Z at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:367) 2024-02-26T12:45:13.072753895Z at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:315) 2024-02-26T12:45:13.072756995Z at java.base/java.lang.reflect.Method.checkCanSetAccessible(Method.java:203) 2024-02-26T12:45:13.072759795Z at java.base/java.lang.reflect.Method.setAccessible(Method.java:197) 2024-02-26T12:45:13.072762695Z at javassist.util.proxy.SecurityActions.setAccessible(SecurityActions.java:159) 2024-02-26T12:45:13.072765296Z at javassist.util.proxy.DefineClassHelper$JavaOther.defineClass(DefineClassHelper.java:213) 2024-02-26T12:45:13.072767696Z at javassist.util.proxy.DefineClassHelper$Java11.defineClass(DefineClassHelper.java:52) 2024-02-26T12:45:13.072770496Z at javassist.util.proxy.DefineClassHelper.toClass(DefineClassHelper.java:260) 2024-02-26T12:45:13.072774596Z at javassist.ClassPool.toClass(ClassPool.java:1240) 2024-02-26T12:45:13.072792697Z at javassist.ClassPool.toClass(ClassPool.java:1098) 2024-02-26T12:45:13.072796597Z at javassist.ClassPool.toClass(ClassPool.java:1056) 2024-02-26T12:45:13.072799497Z at javassist.CtClass.toClass(CtClass.java:1298) 2024-02-26T12:45:13.072802398Z at org.apache.drill.common.util.ProtobufPatcher.patchByteString(ProtobufPatcher.java:77) 2024-02-26T12:45:13.072805198Z at org.apache.drill.common.util.ProtobufPatcher.patch(ProtobufPatcher.java:48) 2024-02-26T12:45:13.072808098Z at org.apache.drill.jdbc.Driver.<clinit>(Driver.java:46) 2024-02-26T12:45:13.072811198Z at java.base/jdk.internal.misc.Unsafe.ensureClassInitialized0(Native Method) 2024-02-26T12:45:13.072813898Z at java.base/jdk.internal.misc.Unsafe.ensureClassInitialized(Unsafe.java:1160) 2024-02-26T12:45:13.072816798Z at java.base/jdk.internal.reflect.MethodHandleAccessorFactory.ensureClassInitialized(MethodHandleAccessorFactory.java:300) 2024-02-26T12:45:13.072820999Z at java.base/jdk.internal.reflect.MethodHandleAccessorFactory.newConstructorAccessor(MethodHandleAccessorFactory.java:103) 2024-02-26T12:45:13.072823999Z at java.base/jdk.internal.reflect.ReflectionFactory.newConstructorAccessor(ReflectionFactory.java:200) 2024-02-26T12:45:13.072827499Z at java.base/java.lang.reflect.Constructor.acquireConstructorAccessor(Constructor.java:549) 2024-02-26T12:45:13.072830299Z at java.base/java.lang.reflect.Constructor.newInstanceWithCaller(Constructor.java:499) 2024-02-26T12:45:13.072832999Z at java.base/java.lang.reflect.Constructor.newInstance(Constructor.java:486) 2024-02-26T12:45:13.072835899Z at java.base/java.util.ServiceLoader$ProviderImpl.newInstance(ServiceLoader.java:789) 2024-02-26T12:45:13.072838699Z at java.base/java.util.ServiceLoader$ProviderImpl.get(ServiceLoader.java:729) 2024-02-26T12:45:13.072841400Z at java.base/java.util.ServiceLoader$3.next(ServiceLoader.java:1403) 2024-02-26T12:45:13.072844300Z at java.sql/java.sql.DriverManager$2.run(DriverManager.java:619) 2024-02-26T12:45:13.072847100Z at java.sql/java.sql.DriverManager$2.run(DriverManager.java:599) 2024-02-26T12:45:13.072850200Z at java.base/java.security.AccessController.doPrivileged(AccessController.java:319) 2024-02-26T12:45:13.072853000Z at java.sql/java.sql.DriverManager.ensureDriversInitialized(DriverManager.java:599) 2024-02-26T12:45:13.072855900Z at java.sql/java.sql.DriverManager.getConnection(DriverManager.java:671) 2024-02-26T12:45:13.072858801Z at java.sql/java.sql.DriverManager.getConnection(DriverManager.java:253) </details> -- This is an automated message from the Apache Git Service.
