PolarStereographic and Orthographic do call static doubleValue() method whose
binding is ambigous
-------------------------------------------------------------------------------------------------
Key: GEOT-2461
URL: http://jira.codehaus.org/browse/GEOT-2461
Project: GeoTools
Issue Type: Bug
Components: core referencing
Affects Versions: 2.5.4
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 2.5.5
The ScriptTest class fails under Java 6 on Linux i386 on the orthographic and
polar stereographic scripts.
The funny thing is that it fails when compiled with java6 even if after that
you run with java5 (the maven compiler is setup for java 5 compliance).
This means the issue is in how the compiler behaves.
Debugging shows that the java5 compiler binds the call to doubleValue() to
AbstractProvider in java5, but to another class (don't remember exactly which
one) in java 6, the former does a conversion from deegree to radians, the
latter does not.
This results in the PolarStereographic transform to be chosen in Java5, whilst
a subclass of StereographicUSGS is chosen in java6, obviously leading to
different results in the transform.
The Eclipse compiler usually returns a warning for calls to static methods
without class qualification (just method() instead of XXX.method()).
This is exactly the reason why.
Makind those two classes explictly call AbstractProvider.doubleValue() fixes
the issue and allows the Java6 build to go on.
