Bug ID: 55149
Summary: Usage of XmlBeans triggers "clearThreadLocalMap"
warnings in Tomcat with XSSF
Product: POI
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: XSSF
Assignee: [email protected]
Reporter: [email protected]
When using POI 3.9 with Apache Tomcat 6, to load, manipulate and save XLSX
worksheets, the following messages appear in catalina.out when stopping Tomcat
using $CATALINA_HOME/bin/shutdown.sh --> this looks like a memory leak.
SEVERE: The web application [/foobar] created a ThreadLocal with key of type
[org.apache.xmlbeans.XmlBeans$1] (value
[org.apache.xmlbeans.XmlBeans$1@7d3aace]) and a value of type
[java.lang.ref.SoftReference] (value [java.lang.ref.SoftReference@5972be65])
but failed to remove it when the web application was stopped. This is very
likely to create a memory leak.

clearThreadLocalMap
SEVERE: The web application [/foobar] created a ThreadLocal with key of type
[org.apache.xmlbeans.impl.schema.SchemaTypeLoaderImpl$1] (value
[org.apache.xmlbeans.impl.schema.SchemaTypeLoaderImpl$1@7c3206c3]) and a value
of type [java.util.ArrayList] (value [[java.lang.ref.SoftReference@385a2be8]])
but failed to remove it when the web application was stopped. This is very
likely to create a memory leak.

[java.lang.ref.SoftReference] (value [java.lang.ref.SoftReference@362f7b99])
but failed to remove it when the web application was stopped. This is very
likely to create a memory leak.

[java.lang.ref.SoftReference] (value [java.lang.ref.SoftReference@2dbaa4d2])
but failed to remove it when the web application was stopped. This is very
likely to create a memory leak.
