Bug #: 52731
Summary: An incomplete fix for the resource leak bug in
JDTCompiler.java
Product: Tomcat 7
Version: trunk
Platform: PC
Status: NEW
Severity: critical
Priority: P2
Component: Jasper
AssignedTo: dev@tomcat.apache.org
ReportedBy: liangg...@sei.pku.edu.cn
Classification: Unclassified
The fix revision 1043157 was aimed to remove an resource leak bug on the
BufferedReader object "reader " (created in line 115), the FileInputStream
object "is" (created in line 112) in the method "getContents()" of the file
"/tomcat/trunk/java/org/apache/jasper/compiler/JDTCompiler.java" , but it is
incomplete.
There are some problems:
1. when "reader" is not created successfully but the temp InputStreamReader is
created successfully at line 114, the temp InputStreamReader will be leaked.
The best way to close such resource objects is putting such close operations in
the finaly block of a try-catch-finally structure.
