Modify the launch to specify JVM arguments (-Xmx<meg>m) for increasing
the heap size.

try the following
- launch ant outside eclipse (nearly always the better way..)
- check your script what it does / should do and correct the error
- give more RAM to your process

Hello All,

Please check 6 Common Errors in Setting Java Heap Size:
Two JVM options are often used to tune JVM heap size: -Xmx for maximum heap size, and -Xms for initial heap size.
* Missing m, M, g or G at the end (they are case insensitive).
* Extra space in JVM options, or incorrectly use =
* Only setting -Xms JVM option and its value is greater than the default maximum heap size, which is 64m. The default minimum heap size seems to be 0.
* Heap size is larger than your computer's physical memory.
* Incorrectly use mb as the unit, where m or M should be used instead
* The heap size is larger than JVM thinks you would ever need
* The value is not expressed in whole number.

As per my Experience, The error java.lang.OutOfMemoryError: Java heap space where there is no more space available for the Java program.

You should debug application and try to find why your application is taking more space.

You can also increase the Java heap space using following parameters while starting your application:

While running Java program from command line java -Xms5m -Xmx15m yourjavafile

While running tomcat set JAVA_OPTS="-Xms256m -Xmx1024m"

Thanks
