The test below shows that jdk1.2b4H throws wrong exception for unexisting
interface javasoft/sqe/tests/vm/classfmt/cpl/cplcls002/cplcls00206m1\u1E00/cplcls00206m1i (\u1E00 - LATIN CAPITAL LETTER A WITH RING BELOW):

How can the bad magic number exist for the unexisting interface?
The test works fine for jdk1.2b3N:

novo7% /export/ld14/java/dest/jdk1.2b3N/solaris/bin/java -verify javasoft.sqe.tests.vm.classfmt.cpl.cplcls002.cplcls00206m1.cplcls00206m1

novo7% echo $status
