The JVM (1.5.0-beta-b28) accepts class v49:0 with
low = 0x80000000 for tableswitch instruction.
Note, the JVM rejects this class file if CF version < 49:0.

The new JCK tests are failed due to this error:
# vm/instr/tableswitch/tableswitch003/tableswitch00310m1t/tableswitch00310m1t.html

The test source:
--------------------- test12_49.jasm ---------------------------
public class test12_49 version 49:0 {
