<DIV dir=ltr><FONT face=Arial><FONT color=#000000 size=2>I run the tests in
one-test mode, so no time outs in previous tests are the reason for IAEE.
The first time I run test "X" everything is fine, deploying jar, binding
home interfaces and finally unbinding home interfaces (what's not true
because there are still visible in the JMXConsole). When I run the test
again I get the IAEE. The whole package org.jboss.test.cmp2.* (over 250
tests) would run without any errors (now over 230 errors), when unbinding
would work correct.</FONT></FONT></DIV>
<DIV dir=ltr><FONT face=Arial><FONT color=#000000 size=2>For example, many
tests have to bind EJBTestRunner to jndi, but only the first test can do it
successfully, the others can't because EJBTestRunner isn't properly unbound
and a repeated bind cause the IAEE.</FONT></FONT></DIV>

any test timeouts. As Adrian mentioned, it is some test failing to
teardown and tests timing out are likely suspects. Debug them
first. If you see no test timeouts, then the problem becomes harder.
