Hi,

the attached is a testcase for javax.
imageio.spi.ServiceRegistry.setOrdering. Checks #3, 4, 5, 6, and 7 fail
on JDK 1.4.1_01. However, I think they all should succeed.

Before I file a bug, I'd like to make sure that it isn't my fault. So,
I'd be glad if anyone could review the test case and tell me whether they
think it should succeed.

You'll have to read the API specification for
javax.imageio.spi.ServiceRegistry.setOrdering in order to understand the
testlet.

http://java.sun.com/j2se/1.5.0/docs/api/javax/imageio/spi/
ServiceRegistry.html#setOrdering(java
lang.Class,%20java.lang.Object,%20java.lang.Object)

Thanks in advance for your help,

-- Sascha
