NativeExceptions have ugly stack traces
---------------------------------------
Key: JRUBY-3890
URL: http://jira.codehaus.org/browse/JRUBY-3890
Project: JRuby
Issue Type: Bug
Components: Java Integration
Reporter: Rib Rdb
Priority: Minor
Attachments: diff
When a NativeException is raised, the stack trace is incredibly difficult to
read. It has way too much information about the JRuby details, and often is
missing the top frame or two of ruby code. For example, here's the trace I
would like to see for an exception I got today:
java.lang.ExceptionInInitializerError: null

Instead, I get the monstrosity below. Notice that create_mac is missing, and
the line number here is particularly important in this case.
Also most of these java frames are just the implementation details of the ruby
frames at the bottom.

The attached patch would at least help clean up some of the redundant java
trace lines.
