There are 23,094 more children
so, some object like 'org/apache/ojb/broker/util/ReferenceMap$Entry',
'org/apache/ojb/broker/util/ReferenceMap' ,
org/apache/ojb/broker/metadata/fieldaccess/AnonymousPersistentField objects
are consuming
more than 1 GB (1,095,332,664 bytes) on heap.
I need an explanation of this , please. and solution or test to do .
thx in advance.
