[jira] [Created] (JUNEAU-90) Could not instantiate class
org.apache.juneau.svl.Var
James Bognar created JUNEAU-90:
----------------------------------
Summary: Could not instantiate class org.apache.juneau.svl.Var
Key: JUNEAU-90
URL: https://issues.apache.org/jira/browse/JUNEAU-90
Project: Juneau
Issue Type: Bug
Components: Code
Affects Versions: 7.2.1
Reporter: James Bognar
Assignee: James Bognar
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.
