peda said on IRC:
I only have a rough idea. the bootimage builder needs to know about the classlayout for internal reasons (memory layout, serialization,..), and for that it loads classes and reflects for fields, and this either happens with JNode's classloader or with Sun ones. we had issues with that before and "fixed" it by agreeing to use sun-jdk 6 Smiling . it was a issue when using sun-jdk 5 back then.
[in openjdk 6,] there were quite some bugfixes, replacement code,..

Anyway, we should be able to build with openjdk imho, so this is a bug.

(Ben says) So, the bug is

to make it work with openjdk in the short term
to write a "bootimage builder" which is not dependent on a particular JDK version or implementation, in the long term
