Re: [cross-project-issues-dev] icu.base and Java 1.5
|
One small correction. org.eclipse.osgi still supports 1.4 and even CDC/Foundation 1.1. The source code for org.eclipse.osgi is using 1.5 (generics etc.) but is being downcompiled to run on J2SE 1.4 (ala jsr14 flag).

While we can still build with the new version, we get an

I wonder if this does not cause problems with other consumers of icu.
As an example, org.eclipse.jface.databinding imports the icu.text
package, even though it has the execution environment
CDC-1.0/Foundation-1.0,J2SE-1.3. Any thoughts?
This won't have an effect on building (ex, org.eclipse.core.resources and org.eclipse.osgi are now at 1.5, but the workbench and IDE build on top of them as BREE: J2SE-1.4). The Eclipse Platform now allows bundles to move to java 1.5, and some have started.
But yes, the Indigo ICU won't run on a 1.4 JVM.
If you require a 1.4 ICU runtime, you need to use the ICU base shipped with 3.6, available in orbit, ex: com.ibm.icu.base_4.2.1.v20100412.jar
