org.apache.maven.BuildFailureException : Compilation failure. The system is out of resources.

Hi,
I've a problem when I'm trying to compile a new version of my application.

fooApp_1.0 has 1905 files, and Maven compiles it right
dooApp_1.1 has 1985 files, and when I try to compile it I'm receive the following error:

org.apache.maven.BuildFailureException : Compilation failure
Failure executing javac, but could not parse the error:

The system is out of resources.

In my pom.xml I'd configured the JDK as:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version> 2.1-SNAPSHOT</version>
<configuration>
<executable>${JAVA_1_4_HOME}/bin/javac</executable>
<fork>true</fork>
<source> 1.4</source>
<target>1.4</target>
<meminitial>128m</meminitial>
<maxmem>1024m</maxmem>
<verbose>false</verbose>
</configuration>
</plugin>

(I got the same error with version 2.0.2 and 2.0.1).

I also tried to set MAVEN_OPTS with:
-Xmx1024m -Xms512m

and

-Xmx1024m -Xms512m -XX:PermSize=128m -XX:MaxPermSize=256m

If I'm using JDK 1.5 to compile, instead of 1.4, I've got this trace:

The system is out of resources.

(about four pages like these ..)

The project compiles fine using the Eclipse and MaveIde (not when I build with Maven, but when I run build-project from Eclipse using maven for the lib-path).
