Myrna van Lunteren commented on DERBY-5419:
-------------------------------------------
For what it's worth, weme (6.2) doesn't set this system property
'microedition.platform' at all.
It does set the following which hint at j2ME or CDC Foundation information:
java.specification.name: J2ME Foundation Specification
java.specification.version: 1.1
java.vm.specification.version: 1.0
java.version: WECE J2ME Foundation Specification v1.1
> Make Derby run on Oracle Java ME Embedded Client

> This seems to happen because Derby recognizes it as a Java 1.4 platform,
> whereas it's actually a CDC/FP 1.1.2 platform.
