Hi Everyone
I am working on bug https://bugs.openjdk.java.net/browse/JDK-7195249.
Based on my colleagues' research,
Root cause:
hotspot/test/runtime/6294277/SourceDebugExtension.java
jdk/test/sun/management/jmxremote/bootstrap/RmiSslBootstrapTest.java
jdk/test/sun/management/jmxremote/bootstrap/RmiBootstrapTest.java
jdk/test/sun/management/jmxremote/bootstrap/SSLConfigFilePermissionTest.sh
jdk/test/sun/management/jmxremote/bootstrap/LocalManagementTest.java
fails intermittently because of use of fixed ports. These ports could be
busy at some configurations.
Suggested fix:
1. My recommendation would be to convert the only shell test
(SSLConfigFilePermissionTest.sh) into
Java based test and re-use the dynamic port allocation
solutionjdk/test/lib/testlibrary/jdk/testlibrary/Utils.getFreePort() to
address the issue for JDK tests. Staffan Larsen recommends to use this
solution instead of java/rmi/testlibrary/TestLibrary.getUnusedRandomPort().
2. For hotspot tests I cannot find appropriate test utils (witch provide
getFreePort() functionality). There are several options:
- copy whole library jdk/test/lib/testlibrary/jdk/testlibrary/ to
hotspot repository;
- copy one class jdk/test/lib/testlibrary/jdk/testlibrary/Utils.java to
hotspot repository;
- copy one method from class
jdk/test/lib/testlibrary/jdk/testlibrary/Utils.java
(Utils.getFreePort()) to hotspot repository;
- move the library jdk/test/lib/testlibrary/jdk/testlibrary/ to a place
that can be shared between hotspot & jdk tests (if such place exists).
3. SourceDebugExtension test uses jtreg tag @run with hard coded port in
jvm options. The test must be converted to test with java based test
launcher and test application (e.g. like the test LocalManagementTest.java).
Please let me know any comments or suggestions.
Thank you
