Peter Palaga updated ELY-1293:
------------------------------
Description:
{{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.
{code}
export JAVA_HOME=path/to/ibm/java8
$JAVA_HOME/bin/java -version
java version "1.8.0"
Java(TM) SE Runtime Environment (build pxa6480sr3fp12-20160919_01(SR3 FP12))
IBM J9 VM (build 2.8, JRE 1.8.0 Linux amd64-64 Compressed References 20160915_318796 (JIT enabled, AOT enabled)

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