mookid8000 opened a new pull request #834: improve error message when JAVA_HOME is set to the wrong value URL: https://github.com/apache/zookeeper/pull/834 This is small (Windows-based) developer usability improvement. When the `JAVA_HOME` environment variable is set, but the value is wrong (so that `JAVA_HOME` + `/bin/java.exe` does not point correctly to `java.exe`), the startup script will simply fail with the message ```dos Error: JAVA_HOME is incorrectly set. ``` which is a bummer. 😞 With this tiny change, the error message will be much friendlier: ```dos Error: JAVA_HOME is incorrectly set: C:\Program Files\Java\jre1.8.0_201\bin Expected to find java.exe here: C:\Program Files\Java\jre1.8.0_201\bin\bin\java.exe ``` (in this case showing a situation where one has inadvertently included `/bin` in the `JAVA_HOME` environment variable). This will also give a nicer error message in situations, where the JRE has been updated, and the one pointed to by `JAVA_HOME` has been uninstalled.
