Hi all!

It looks like we have a regression in loading Java classes with upper case package names. Works fine in JRuby 1.7.19, but fails with JRuby 1.7 head:

$ cat org/TestApp/TestClass.java
package org.TestApp;

public class TestClass {
    public static void hello() {
        System.out.println("Hello!");
    }
}

$ javac org/TestApp/TestClass.java

$ rvm use jruby
Using /Users/uwe/.rvm/gems/jruby-1.7.19

$ ruby -J-Djruby.ji.upper.case.package.name.allowed=true -S irb
jruby-1.7.19 :001 > Java::org.TestApp.TestClass.hello
Hello!
 => nil 
jruby-1.7.19 :002 > exit

$ rvm use jruby-17-head
Using /Users/uwe/.rvm/gems/jruby-17-head

$ ruby -J-Djruby.ji.upper.case.package.name.allowed=true -S irb
jruby-17-head :001 > Java::org.TestApp.TestClass.hello

Thanks @kares !

@kares
avoid regression in loading Java classes with upper case package names (
7d9d2ba 
fixes jruby#2742)

... caused by the internal cleanup (the regression is not part of any 1.7.x release)

one can only test this with *-Xji.upper.case.package.name.allowed=true* but since there's another failure the feature introduces, this will need to be revisited

Hi @kares !

Thanks for the fix. The initial test case is now working with JRuby commandline, but I still have a failing test case in Ruboto, the one that initiated my report.

The test case is simple and fails consistently in my local work space, but succeeds in travis-ci. I will investigate a bit more and come back to you.

OK, thanks for the feedback @donv ... please be sure to let me know if there's any regression ...

for me running test:jruby19 with ji.upper.case.package.name.allowed=true still shows one failure but that one pretty sure failed previously.I hoped for your case to be covered with the added test ;(

Hi @kares !

It now looks like everything is OK. I am not sure what changed, but my tests are green.

Consider this fixed. I'll report if there is a regression.
