I've tried something here

[oe] [meta-java][RFC][PATCH 1/7] openjdk-8-native: add meaningful (R)PROVIDES
[oe] [meta-java][RFC][PATCH 2/7] layer.conf: allow multiple Java SDKs & runtimes to co-exist
[oe] [meta-java][RFC][PATCH 3/7] openjdk-8: add meaningful (R)PROVIDES
[oe] [meta-java][RFC][PATCH 4/7] openjre-8: add meaningful (R)PROVIDES
[oe] [meta-java][RFC][PATCH 5/7] layer.conf: set defaults for Java JRE (R)PROVIDERS
[oe] [meta-java][RFC][PATCH 6/7] openjdk-7: (R)PROVIDE virtual Java [567] packages
[oe] [meta-java][RFC][PATCH 7/7] ca-certificates-java: switch to more generic / more correct JAVA (R)DEPENDS


the idea is to add virtual (R)PROVIDES that other recipes can depends on,
similar to e.g. Debian.

I'm using this locally, but I think there are some corner cases that aren't handled.
