[richfaces-issues] [JBoss JIRA] Created: (RF-8134) Memory leak in the in-process template compiler.

Memory leak in the in-process template compiler. ------------------------------------------------ Key: RF-8134 URL: https://jira.jboss.org/jira/browse/RF-8134 Project: RichFaces Issue Type: Bug Affects Versions: 3.3.2.SR1 Reporter: Alexander Smirnov In-proces compiled templates are widely used by dynamic stylesheets or complonents like suggestionBox. These templates are compiled into in-memory object structures what usually have only one instance in application. These objects are called with special context to generate request output ( lightweight object pattern ). <f:call element > caches call parameter values in its instance, even FacesContext or current component references that are short-time objects. As a results, memory leaks are occured in the org.ajax4jsf.rendercit.compiler.MethodCallElement class. The source of problem are inner Signature1 and Signature2 classes: Signature1(int size) { arguments = new Object[size + 1]; } void update(TemplateContext context, Object[] parameters) { arguments[0] = context; System.arraycopy(parameters, 0, arguments, 1, parameters.length); } } class Signature2 extends Signature { Signature2(int size) { arguments = new Object[size + 2]; } void update(TemplateContext context, Object[] parameters) { arguments[0] = context.getFacesContext(); arguments[1] = context.getComponent(); System.arraycopy(parameters, 0, arguments, 2, parameters.length); } To avoid memory leaks, only types of the target method should be cached ( not object instances ). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
