How to check the version of Java in Notes

There are three options:
OPTION 1:

About IBM Lotus Notes
-- In Notes, select Help -> About IBM Lotus Notes
-- Click the "Configuration Details" button and look for the following line

    java.runtime.version=pwi3260sr12ifx-20121108_01 (SR12)



OPTION 2:

Issue "java -version" command
-- In Command Prompt, navigate to jvmbin
-- Issue the command java -version
-- The output should appear as follows:

java version "1.6.0"
Java(TM) SE Runtime Environment (build pwi3260sr12ifix-20121108_01(SR12+IV31417))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Windows 7 x86-32 jvmwi3260sr12-20121024_126067 (JIT enabled, AOT enabled)
J9VM - 20121024_126067
JIT  - r9_20120914_26057
GC   - 20120928_AA)
JCL  - 20121108_01

Note : If you do not issue "java -version" from within the jvmbin directory, the system JVM version will be returned instead of the Notes JVM version.


OPTION 3:

-- In Notes select Tools ->  Show Java Debug Console

there you can enter commands in the upper part of the debug-window  

v   -> version

h -> help
