JDK 1.3L fails the following JCK(114a, 116a, 12a) test:

vm/instr/astore_w/astore_w004/astore_w00401/astore_w00401.html

which contains method with 65535 locals.

"The greatest number of local variables in the local variables array of a frame
created upon invocation of a method is limited to 65535 by the size of the max_locals
item of the Code attribute ($4.7.3) giving the code of the method."
(JVMS, second edition, CHAPTER 4 The class File Format,
section 4.10 Limitations of the Java Virtual Machine)

The failure is reproduced only when hotspot VM is used.
The test is passed under -classic mode.

See reduced test case and logs below.
