Re: [aspectj-users] OutOfMemory error in aspectj
|
Hi Andy,
I finally nailed the bug. The reason I was getting an OOM even though
I increased the memory was because I am using ajc script from the
command line which invokes the jvm with 64M. So, the option I give the
ajc doesn't really increase the memory of the JVM.
This bug went unnoticed for these reasons:
1) ajc was a script. I think it was a bad idea for a script to set the
maximum heap space. I think it should just leave the default JVM
value.
2) org.aspectj.tools.ajc.Main should not take a -Xmx option. It
shouldn't because it doesn't affect the heap space. If the user
provides it , ajc should exit with the message saying that this is an
incorrect option.
3) The log file generated by ajc shows the -X option provided by user
and not the heap space the JVM is using (64M in this case).
---- Command Line ---
-Xmx4096m
This is incorrect because on a 32 bit machine a process can't have
that much memory. Also, it was a dummy value which is not being used.
All these things gave me a false impression that I was running out of
4G of memory when I was not.
I think the simplest fix is to fail when a user provides -X option. I
just wasted 2 weeks of my life chasing a bug that didn't exist. Please
fix this. I can send a patch if you want.
