问题 I have three very simple applilcations. One is COMMON which I will center security configs, other with ZUUL feature and the third is a EUREKA SERVER. Both are Spring Boot and Java 11. Although I am using Java 11 I am not reling on modularity (as far as I know it will not make sense use modularity feature with Spring Boot). When I run all three in Eclipse I successfully can run the server, common and zuul in that sequence. When I try to maven build I get the error mentioned in subject. The

问题 I just installed Oracle JDK 11 on my Windows 10. I noticed that the PATH variable doesn't include the JDK 11 path. Also the .JAR file extension is not associated with javaw. Our users used to doubleclick JAR file to execute the client Java/SWING application. With Java 11 this doesn't work. Is this a bug or feature? I know how to set the PATH and start the application manually using the command line. I just want to make it easier for end-users. Any ideas? 回答1: There is no Public JRE in Java 11

问题 My software builds use -Xlint -Werror so I routinely run across compiler warnings that break my build. Every once in a while I run across a warning that I need to suppress, but it's always difficult to figure out which Xlint option suppresses the warning I am seeing. I'll give you a concrete example. I recently ran across: [WARNING] module-info.java:[16,106] module not found: org.bitbucket.cowwoc.requirements.guava I searched the JDK 11 source-code and discovered this warning message declared

问题 JEP 330 describes a new feature in JDK 11 for launching single-file programs in Java. I've tried: $ ./Example.java but it doesn't work.

问题 When compiling with ant , calls to sun.awt.AppContext work, however the same code compiled with IntelliJ fails using AdoptOpenJDK11. sun.awt.AppContext with Oracle JDK8 works with IntelliJ sun.awt.AppContext with AdoptOpenJDK11 does NOT work with IntelliJ Although Sun/Oracle has warned for a while about avoiding the sun.* packages, there are certain features (bugs?) in Java that still require them and stranger, the command line seems happy.

问题 I am migrating our code base from Oracle Java 1.8.0_131 to OpenJDK 11.0.1. We have code that implements nio-ssl socket channels. In Java 8, the client/server handshake works fine. In Java 11, the client finishes the handshake before it unwraps the last handshake message from the server. To produce this problem, I am just establishing a connection between the client and server and letting them perform a SSL handshake. I am NOT sending any additional data through. I establish the connection
