Bug ID: 57783
Summary: NPE in SlowQueryReport - getQueryStats() returning
null
Product: Tomcat Modules
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: jdbc-pool
Assignee: dev@tomcat.apache.org
Reporter: mazu...@gmail.com
I'm running Tomcat 7.0.52 (7.0.52-1ubuntu0.1) with jdbc-pool and I see this
exception in catalina.out somewhat frequently:
Mar 30, 2015 11:44:44 PM
org.apache.tomcat.jdbc.pool.interceptor.AbstractQueryReport createStatement
WARNING: Unable to create statement proxy for slow query report.
java.lang.NullPointerException
at
org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReport.prepareStatement(SlowQueryReport.java:122)
As far as I can tell, it appears unrelated to #51582. In this case, some
condition causes getQueryStats() to return null:
public void prepareStatement(String sql, long time) {
QueryStats qs = getQueryStats(sql);
qs.prepare(time); // <--- LINE 122
}
Please let me know if you need any more info.
