Bug ID: 67664
Summary: IllegalArgumentException in
ConnectionPool.getProxyConstructor
Product: Tomcat Modules
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: jdbc-pool
Assignee: dev@tomcat.apache.org
Reporter: t...@silbergrau.com
Target Milestone: ---
With the update to tomcat 9.0.81 (due to the released CVE) we run into an
IllegalArgumentException.
Looking at the previous implementation before (9.0.80), it seems like some
refactoring issue. I hope i chose the right project/component and I didnt find
a similar bug report yet.
Previous implementation did
Proxy.getProxyClass(ConnectionPool.class.getClassLoader(), new Class[]
{java.sql.Connection.class,javax.sql.PooledConnection.class});
New implementation is
Proxy.getProxyClass(ConnectionPool.class.getClassLoader(), new Class[]
{Connection.class,PooledConnection.class});
-> Connection has import to java.sql.Connection.class and works as before.
-> PooledConnection has no import and now resolves to
org.apache.tomcat.jdbc.pool.PooledConnection and leads to the
IllegalArgumentException (was javax.sql.PooledConnection previous).
