[SOLVED] How do we get SR and FP of IBM JRE using Java?

How do we get SR and FP of IBM JRE using Java?

How do we get the below details from Java code? Particularly SR and FP details.

java version "1.7.0"
Java(TM) SE Runtime Environment (build pap6470_27sr1fp1-20140708_01(SR1 FP1))
IBM J9 VM (build 2.7, JRE 1.7.0 AIX ppc64-64 Compressed References
20140707_205525 (JIT enabled, AOT enabled)
J9VM - R27_Java727_SR1_20140707_1408_B205525
JIT  - tr.r13.java_20140410_61421.07
GC   - R27_Java727_SR1_20140707_1408_B205525_CMPRSS

JCL - 20140707_01 based on Oracle 7u65-b16

Solution

That information is put together from the System properties. To find the appropriate set of properties, run java -XshowSettings:properties.

In this case, the property you want is the java.runtime.version which has a value like: pxi3270_27sr4-20160303_03 (SR4). You can parse the SR / FP out of the brackets. If there isn't one, then it's the GA level.
