Error: code too large for try statement, when compiling a big java file.

Question

Hi,
I have a big java file ( around 16000 lines). When compiling it, I got following error message:
MyMain.java:15233: code too large for try statement
} catch ( Throwable t ) {
In MyMain.java, I just repeat following statements about 1000 times.
try {
if ( year >= 2002 ) {
System.out.println( "year: Evaluation version is not valid" );
} else {
System.out.println( "year: Evaluation version is still valid" );
} catch ( Throwable t ) {
if ( year >= 2002 ) {
System.out.println( "year: Evaluation version is not valid" );
} else {
System.out.println( "year: Evaluation version is still valid" );
I tried 1.3 and 1.4 javac compiler, there was some error.
How to make compiler to compile this code?
Thanks,

You don't. Each method has an absolute limit on the number of byte codes. You have reached that limit. The limit is part of the specification and JVMs will refuse to run classes that exceed the limit. So even if you could compile it, it wouldn't run.
It is quite common for code generators to generate large monolithic blocks of code. Presumably this is how you got to this spot. Modify the code generator to break it into smaller blocks.
If you did it manually then you did it wrong. And you will have to manually break it into smaller blocks. (And re-examine your design since it is probably wrong.)
