Bug #: 53081
Summary: WebappClassLoader causes java.lang.OutOfMemoryError in
findResourceInternal()
Product: Tomcat 7
Version: 7.0.26
Platform: PC
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: dm...@mail.ru
Classification: Unclassified
When examining the code of WebappClassLoader#findResourceInternal()
(http://grepcode.com/file/repo1.maven.org/maven2/org.apache.tomcat/tomcat-catalina/7.0.26/org/apache/catalina/loader/WebappClassLoader.java#3098)
I came to the conclusion that findResourceInternal() always loads the binary
content of the resource, however binary content is only used in e.g.
findClassInternal() and obviously not needed in findResource(). In certain
cases this can cause OutOfMemoryError, for example when a big media file is
packaged with application.
The example of stack trace is given here:
http://stackoverflow.com/questions/10100480
Solution: the binary content should be loaded for certain types of resources
(.classpath or .properties [only if fileNeedConvert is true]).
