Re: [mdt-ocl.dev] Probable move to Java 7 classes for Eclipse OCL in Mar

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi

The move to Java 7 was not so easy. [1] There are 7 smelly templated operation such as OCL.newInstance that cannot be compiled as-is by Java 7. Changing the code so that the source matches the Java 5 erased signature probably gives binary compatibility but introduces a source incompatibility that probably affects nobody.

However a source incompatibility is not desirable, so for now (so long as EMF manages to remain with a Java 5 BREE) the Classic OCL plugins remain unchanged at Java 5 BREE. The Pivot OCL plugins have moved to Java 7 BREE.

Since the Java 7 pack200 cannot pack all Java 5 bundles [2], org.eclipse.ocl will be distributed without a *.pack.gz. [3]

Hi Ed,

I also inclined to move to Java 7 for QVTo plug-ins.  And I see no reasons to ask OCL not to move to Java 7.

Hi

Some of the Eclipse platform plugins moved to Java 7 classes for Mars M6 and this is causing problems continuing to provide Java 5 (Classic Eclipse OCL) or Java 6 (Pivot Eclipse OCL) plugins. See [1].

The simple solution is to just shift all Eclipse OCL plugins to Java 7 classes.

An alternative is to omit the 'tampered' *.pack.gz files for Mars, and re-introduce them after Mars when the Eclipse OCL build may move to Tycho from Buckminster.

Does anyone have a use case for not moving to Java 7 and so removing all support for Java 5 and Java 6?

(And while I'm asking, does anyone have a problem moving to Java 8 for Mars+1?)
