Description Praveen Puri CLA 2004-12-02 02:38:54 EST 
I am trying to compile my project using AspectJ compiler v1.1.1. My Project has 
nearly 1000 java files. But everytime I compile, I 
get "java.lang.OutOfMemoryError". I have tries compiling my project in parts 
also, but it gives the same error, while compiling 200 files together. I can 
not afford to compile less than these files at a time, as these are in 
different packages also. Exact compiler options I am giving is....

C:\jdk1.4.2_04\bin\java -cp C:\progra~1\JBuilder9
\lib\ext\aspectjrt.jar;C:\progra~1
\JBuilder9lib\ext\aspectjtools.jar;D:\Temp\RecordsManager\lib-extract\ALL 
org.aspectj.tools.ajc.Main -g -d "D:\~Working\FileNet\RecordsManager\WEB-
INF\classes" -sourceroots "com\filenet\wcm;com\filenet\rm;com\filenet\portal" 
1>compile_log.txt 2>&1 

And exact text of error is.....
java.lang.OutOfMemoryError
D:\~Working\FileNet\RecordsManager\Source\com\filenet\wcm\apps\server\ui\WcmPlug
InModule.java:0 Internal compiler error
java.lang.OutOfMemoryError

ABORT
Exception thrown from AspectJ 1.1.1

Please look into this asap. 

I get the same error, If I try to compile the same code from JBuilder (with 
AspectJ plugin).

Regards,
Praveen

Two things spring to mind.

First, from the list of compiler options, you don't seem to be specifying a
large heap setting?  The default for the JVM is 64M I think, which isn't very
much at all.  Can you try by specifying '-Xmx256M' or '-Xmx512M' to supply more
memory?

Second, 1.1.1 is an old version of AspectJ - 1.2.1 is now out and improves
memory usage and compile/weave times - can you switch to this new version?

let me know what happens.
Comment 2 Praveen Puri CLA 2004-12-02 04:22:46 EST 
The problem has been resolved by using '-Xmx256M' option in compiler options. 
But this option is not accepted by AspectJ plugin in Jbuilder. I guess, this is 
not the right place to discuss about that plugin. Anyway I am able to compile 
now through command prompt after increasing heap size.

Thanks,

Praveen

For JBuilder, add the following line to your <jbuilder>/bin/jbuilder.config 
file:

vmparam -Xmx256m

Or more if you find it still running out.
