oleg-zinovev commented on issue #1446: DRILL-6349: Drill JDBC driver fails on Java 1.9+ with NoClassDefFoundError: sun/misc/VM URL: https://github.com/apache/drill/pull/1446#issuecomment-432165721 '@oleg-zinovev, Is it make sence to move these two dependencies to the root pom?' @vvysotskyi, it isn't make sence at all, so i remove this dependencies. I try to build Drill with fresh JDK 11 and fix new errors: 1) JMockit 1.39 -> 1.43. JMockit had an issue with java 11 (https://github.com/jmockit/jmockit1/issues/534), so I had to update this dependecy. Starting JMockit 1.42, "-javaagent" must be specified to run tests (http://jmockit.github.io/tutorial/Introduction.html#runningTests) and jmockit.integration.junit4.JMockit.class was removed. That's why i have to change this tests: - TestCastFunctions.java - TestConstantFolding.java - TestDateConversions.java - TestDateFunctions.java - TestExtendedTypes.java - TestUtf8SupportInQueryString.java - AvroFormatTest.java 2) BoundsCheckingTest.java fails with IllegalAccessException. This was fixed by adding a call of setAccessible(true). 3) JDKClassCompiler.java - Java 11 intoduces 'Nests' (http://openjdk.java.net/jeps/181), and resulting byte-code, generated by javac 11 requires a "Nests" support from ASM visitors. Since Drill supports java 1.8+ i simply add a target and source version to javac call, to not have to change ASM visitors. 4) hadoop 2.7.1 -> 2.7.4. Haboop org.apache.hadoop.util.Shell class in version 2.7.1 contains a Java version check: "System.getProperty("java.version").substring(0, 3).compareTo("1.7") >= 0;" But, for jdk 11 (at least for OpenJDK Ubuntu package), System.getProperty("java.version") return "11", and substring call fails. I had to update hadoop to minimal version, which not contains this call. 5) TestImpersonationMetadata.java - in hadoop 2.7.4 error message was changed, so i slightly change a "expected" error to fit both new and old messages. 6) maven-source-plugin fails to execute "jar-no-fork" on JDK 11, and i update it to the latest version. Now on java 11 fails: 1) HBase tests 2) Hive test I will try to update a HBase and revalidate drill on JDK 9 and JDK 10 to the end of the week. P.S. I am sorry for possible mistakes because of my bad English
