Martin Choma created ELY-1327:
---------------------------------
Summary: System.currentTimeMillis() cannot be mocked on IBM JDK
Key: ELY-1327
URL: https://issues.jboss.org/browse/ELY-1327
Project: WildFly Elytron
Issue Type: Bug
Reporter: Martin Choma
Assignee: Peter Palaga
Fix For: 1.1.0.CR3
{{System.currentTimeMillis()}} is native in IBM JDK and at the same time, IBM JDK does not
support java.lang.instrument API for native methods. Therefore,
{{System.currentTimeMillis()}} cannot be mocked on IBM JDK using jmockit.

Expected: the tests mocking {{System.currentTimeMillis()}} should pass
Actual: the tests mocking {{System.currentTimeMillis()}} throw the following exception or
similar:
