high memory demand prevents reporting huge data source

JasperReports has relatively low limit to print huge reports, that is about 300 mbytes for in-memory JRDataSource object. It appears JasperReports allocates too much additional memory to fill report. Running process takes over 1300 mbytes in memory that is around a limit on 32 bit system. Larger reports fail with OutOfMemoryError.
