Bug#552504: java.lang.IllegalAccessException in Cacao does not occur in Zero
Matt Magoffin
Version: 6b16-4
Found this exception when using Hsqldb 1.9
(http://sourceforge.net/projects/hsqldb/files/alpha_beta/hsqldb_1_9_0_rc6/hsqldb-1.9.0-rc6.zip/download)
that occurs when using the Cacao but not Zero VM in OpenJDK.
