Thorsten Sch=C3=B6ning commented on AXIS2-4094:
------------------------------------------

I have the same issue with current Tomcat 7 and Axis2 1.6.2: Even if I stop=
 the Axis2 service the jars in the lib dirs of the distinct services stay l=
ocked and can't be replaced. Things like telling Tomcat not to lock jars di=
dn't work for me, so I guess it's really Axis2 locking things and Tomcat si=
mply doesn't know about it.

ing+under+Windows
http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Standard%20Impl=
ementation

As a workaround one can use the "Find leaks" button in the bottom of the To=
mcat manager app, which triggers a full garbage collection. After hitting t=
hat button Axis2 seems to get completely unloaded from memory and all locke=
d files are unlocked. Sometimes Tomcat notes that Axis2 leaked memory even =
if it has been stopped, sometimes not... Luckily this functionality is avai=
lable for ANT as well, if you need to automatically deploy some Axis2 servi=
ces, like I do:
