Minecraft's launcher is a bundled app, and OpenJDK currently only supports command-line invocation. We are planning to support bundled apps in OpenJDK by completely replacing the launch infrastructure with one that uses an embedded .jre bundle, and obsoleting the JavaApplicationStub. This has the benefit of offering a completely self-contained app bundle, which is desirable for many reasons.

Also, the graphics plumbing in OpenJDK currently does not support the CALayer-based JAWT API recently introduced to Apple's Java SE 6, so there is no way for Minecraft to attach it's LWJGL surface to the OpenJDK heavyweight windows at this time.

We actively working on both of these problems right now. Please sit tight...the gnomes are still hard at work...
