The Java VM Spec, 3rd edition, sec 4.7.3, page 78:
|
|
|
172 |
|
|

173 |
The fact that end_pc is exclusive is a historical mistake in the design of the
|
|
|
174 |
Java virtual machine: if the Java virtual machine code for a method is exactly
|
|
|
175 |
65535 bytes long and ends with an instruction that is 1 byte long, then that
|
|
|
176 |
instruction cannot be protected by an exception handler. A compiler writer can
|
|
|
177 |
work around this bug by limiting the maximum size of the generated Java
|
|
|
178 |
virtual machine code for any method, instance initialization method, or static
|
|
|
179 |
initializer (the size of any code array) to 65534 bytes.
