Reduce memory footprint of Templates instances
----------------------------------------------
Key: XALANJ-2407
URL: https://issues.apache.org/jira/browse/XALANJ-2407
Project: XalanJ2
Issue Type: Improvement
Components: XSLTC
Affects Versions: 2.7
Reporter: Mike Atkin
Priority: Minor
Fix For: 2.7.1
TemplatesImpl retains the bytecode byte[]s for the compiled xsls even after
generating the translet classes when there appears no reason for it. This
significantly increases memory usage of Templates objects (by an order of
magnitude). In my application (a small low-volume web app) which keeps a
HashMap of 100 or so Templates, 40% of the heap space (64mb configured) is
taken up by this data.
Setting the _bytecodes field to null (possibly adding a system flag or property
to control this) at the end of the defineTransletClasses() method in
TemplatesImpl fixes this.
