oom at javadoc time

I see this error when building on CentOS 5 (32bits) on a VM with 2Gb RAM :

../../src/share/classes/java/util/streams/TerminalSink.java:43:

../../src/share/classes/java/util/streams/ops/ShortCircuitTerminalOp.java:46:

I didn't appears on 64bits instances also with 2Gb RAM.

Any ideas ?
