[cross-project-issues-dev] Possible source incompatibility in Indigo with the new ICU4J 4.4.2
Indigo (Eclipse SDK 3.7.0) will include a newer version of ICU4U, com.ibm.icu 4.4.2, to be included in Indigo M6 (it's already available in the Eclipse SDK I-builds). This move includes bug fixes, but also ICU4Js BREE moves to J2SE-1.5. This will ease the ability of applications to swap in more current versions of ICU4J: 4.6.x and 4.8.0 (due out in May) are based on J2SE-1.5.
WTP found a source code incompatiblity in moving up to ICU4J 4.4.2. In 4.2.x it was possible to write code like:
Comparator<String> STRING_COMPARATOR = Collator.getInstance();
This worked because ICU4J 4.2.x was still J2SE-1.4 (no generics) and the above code simply produced a warning. Now the Collator is defined the same as the JCL, as a Comparator<Object>, the above code will generate a compile error. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=337699
This should not effect binary compatibility (bundles already compiled are fine).
