Regression check: run mauve java.lang.Math tests and report results

[LSantha]

Objective

Use the jnode-interact skill simple mode to boot JNode into tests mode (GRUB entry 4), run the mauve java.lang.Math test suite, and report PASS/FAIL counts.

Instructions

Use the jnode-interact skill (.opencode/skills/jnode-interact/). Boot with GRUB entry 4 (tests), wait for the serial console, then run:

mauve-plugin gnu.testlet.java.lang.Math

Report the number of tests passed/failed and the full FAIL lines.

FAIL: gnu.testlet.java.lang.Math.MathTest: test_rint - 1 (number 0)
FAIL: gnu.testlet.java.lang.Math.MathTest: test_rint - 2 (number 0)
