1768708 - OutOfMemoryError: Java heap space - Error in SWPM (Export)

Symptom

Software Provisioning Manager tool (SWPM) stops the export during step JMigmonExportJ2EEDatabase because one of the packages failed due to the following error:

java.lang.OutOfMemoryError: Java heap space

SWPM does not show a clear error message in the pop message. Checking the sapinst_dev.log file, a similar message like below is found:
