Not possible start Spring Cloud Data Flow in Windows

[manueljordan]

In Windows 10 Home edition, I have configured the JAVA_HOME and PATH variables (same approach used since Windows XP) all my app that use Java work fine, same appreciation for any tool that needs Java, such as (IDE, LibreOffice, etc...)

Observe the following:

> javac -version
javac 1.8.0_131

> java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

According with Spring Cloud Data Flow

When I do java -jar spring-cloud-dataflow-server-local-1.2.2.RELEASE.jar the following happens:

> java -jar spring-cloud-dataflow-server-local-1.2.2.RELEASE.jar

First time I have this behavior. It only happens in Windows 10 Home Edition (not tested in other previous versions), in Mac it works fine about to execute in peace the java -jar spring-cloud-dataflow-server-local-1.2.2.RELEASE.jar command.

Not sure what is missing or how fix this.

I'm moving this and re-creating this ticket in spring-cloud/spring-cloud-deployer-local#58. It's a bug and should be easy to fix.

There seem to be a quick workaround until we get this fixed.

copy java.exe java

Thanks @jvalkeal , I did not test your solution yet. Seems is necessary work around through SPRING_CLOUD_DEPLOYER_LOCAL_JAVA_CMD
