Java Development Kit 9, the next edition of standard Java, had been proceeding toward its planned July 27 release after earlier bumps in the road over modularity. But now Red Hat and IBM have opposed the module plan. “JDK 9 might be held up by this,” Oracle’s Georges Saab, vice president of development for the Java platform, said late Wednesday afternoon. “As is the case for all major Java SE releases, feedback from the JCP [Java Community Process] may affect the timeline. Based on more than two years of feedback from weekly preview builds, we’re confident it meets the goals of the JSR [Java Specification Request] and the needs of developers.”
