I am doing a JProbe testing on a use-case. Inspite of closing all open resources (resultset and PreparedJDBCStatement) , the snapshot(Jprobe) reports instances of OracleStatement on the heap. The memory of this is considerably high . I wish to know why these instances were not garbage collected by the JVM. The application uses Oracle type 4 driver.
The instance view detail lists a number of T4CNumberAccessorXXXXXXX(rowSpaceChar). What is this?
Requesting replies ASAP!. Thanks in advance

JProfiler allows you to find the root of of reference tree, i.e. finding out which object is holding the referenced objects from being garbage collected. Not sure whether JProbe can do something similar.
And I have no idea what a T4CNumberAccessorXXXXXXX(rowSpaceChar) is, sorry.
