A DESCRIPTION OF THE PROBLEM :
We are compile our applikation, and get this message
(its only what I think is the intresting)
 [javac] /proj/zi/vobs/main/sys/src/subsystems/base/main/java/se/rsv/zi/util/sign/ZiSignatureNonce.java
    [javac] /proj/zi/vobs/main/sys/src/subsystems/base/main/java/se/rsv/zi/ws/ZiWebServiceContext.java

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Sorry - I don't think you can.

Its about 20 directories and a lot of java classes.
The java classes have circular dependences.
And there i one build.xml file

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
BUILD SUCCESSFUL

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Compile again - then we get BUILD SUCCESSFUL

I think that we reach some maximum limit of something.
Do you have any proposal ??

  To ant can we send some instructur like
increase maxPermSize
ANT_OPTS="-XX:MaxPermSize=128m"

or another example
<java classname="weblogic.jspc" classpath="${war.jsp.classpath}"
fork="true" failonerror="true" maxmemory="512M" >
