Hi all.
After some thorough research and with help of fellow igniters, I’ve managed to prepare more or less stable Java 9 build configuration of Apache Ignite. Here are changes to make it work: - Java 8 profiles and build process revision, made in IGNITE-7203; - Java 9 maven profile prepared in IGNITE-7144 (will be moved to IGNITE-6730 as subtask); - specific maven-compiler-plugin configuration with JVM args for Java 9 profile (as was proposed by Vladimir Ozerov); - maven-bundle-plugin version is updated to 3.5.0; - maven-compiler-plugin version synchronised to 3.7.0 (in Cassandra modules); - scala version updated to 2.12.4; - disabled scalar-2.10, spark-2.10 and visor-console-2.10 modules (due to dependency in scala 2.10 which is unsupported by Java 9); - sun.misc.JavaNioAccess import changed to jdk.internal.misc.JavaNioAccess in GridUnsafe.java and PageMemoryImpl.java; - sun.misc.SharedSecrets import changed to jdk.internal.misc.SharedSecrets in GridUnsafe.java and PageMemoryImpl.java; - methods monitorEnter and monitorExit bodies commented out (fix from IGNITE-6736 did not work). I’d like to put these changes into ignite-6730 to have working compiling under Java 9 branch — so that we can continue work on improving Apache Ignite’s Java 9 support.
