------------------------------------

This problem occurs when the system property "sun.java.command" is not available in the JVM.

>             Project: Juneau
>          Issue Type: Bug
>          Components: Code
>    Affects Versions: 7.2.1

> I'm having a very odd problem when trying to test deployment of an 
> application I have recently updated to use Juneau 7.2.x.  The problem 
> appears to be specific to certain Windows environments.
> When I call a GET or POST against the application deployed in Tomcat, I 
> get a 500 server error.  Tomcat logs report the cause as:
> org.apache.juneau.FormattedRuntimeException: Could not instantiate class 
> org.apache.juneau.svl.Var
> This appears to be caused by a npe:
> org.apache.juneau.internal.ClassUtils.newInstanceFromOuter(ClassUtils.java:1871)
>         ... 26 more
> Caused by: java.lang.NullPointerException
>         at java.util.Objects.requireNonNull(Objects.java:203)
>         at java.util.Arrays$ArrayList.<init>(Arrays.java:3813)
>         at java.util.Arrays.asList(Arrays.java:3800)
>         at org.apache.juneau.utils.Args.<init>(Args.java:115)
>         at org.apache.juneau.utils.Args.<init>(Args.java:149)
>         at org.apache.juneau.svl.vars.ArgsVar.<init>(ArgsVar.java:86)
> (Interestingly I am having trouble getting the log4j logging to work in 
> this environment also, but that may be unconnected)
> This app works fine in:
>   - Windows based Eclipse development environment (using Maven 
> tomcat7:run goal to spin up a server)
>   - Tomcat 9 deployment on MacOS
> Fails in:
>   - Windows Tomcat 8.5 environment on different Windows Server 2009 R2 
> machine
>   - Windows Tomcat 8.5 environment on Windows 10 desktop
> I've tried both IBM and Sun JREs, most recently an Oracle 1.8.0_192-b12 
> - this does not change the result.
> I've tested with both 7.2.0 and the 7.2.1 RC, with the same results.
