Does Cassandra support Java 10?

阅读更多关于 Does Cassandra support Java 10?

问题 We're planning on migrating our environment from Java 8 to OpenJDK 10. Doing this on my local machine, I've found that Cassandra will no longer start for me, giving the following error : I can't find any solid information online that says it is definitely not supported. This post from 4 months ago suggests that they do not support Java 10, but doesn't say it is confirmed, and is more inferred. There is also a comment on it from another user saying they have managed to get it running on Java

阅读更多关于 Eclipse can't find XML related classes after switching build path to JDK 10

问题 I\'m developing on a Maven project (branch platform-bom_brussels-sr7) in Eclipse. When I recently tried switching the Java Build Path for the project to JDK 10, Eclipse build can no longer find classes such as javax.xml.xpath.XPath , org.w3c.dom.Document , or org.xml.sax.SAXException . It seems only XML related classes are impacted, mostly from the Maven dependency xml-apis-1.4.01 . Trying a Maven build from Eclipse works without errors.

How to resolve java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException in Java 9

阅读更多关于 How to resolve java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException in Java 9

问题 I have some code that uses JAXB API classes which have been provided as a part of the JDK in Java 6/7/8. When I run the same code with Java 9, at runtime I get errors indicating that JAXB classes can not be found. The JAXB classes have been provided as a part of the JDK since Java 6, so why can Java 9 no longer find these classes? 回答1: The JAXB APIs are considered to be Java EE APIs, and therefore are no longer contained on the default class path in Java SE 9.
