Hi Andrey,
When i tried your example, It is not returning any values
require 'facter/util/file_read'
=> true
irb(main):005:0> log =
Facter::Util::FileRead.read("/home/suppalapati/java.txt")
=>
"\n/usr/java/jdk1.7.0_25/jre/bin/java\n/usr/java/jdk1.7.0_25/bin/java\n/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.45.x86_64/jre/bin/java\n/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/bin/java\n\n"
irb(main):006:0> log.each_line do |line|
irb(main):007:1* javaid, val = %x{line}
irb(main):008:1> javaid, val = %x{java}
irb(main):009:1> val = %x{java}
irb(main):010:1> val = %x{line}
irb(main):011:1> val = %x{log}
irb(main):012:1> val = %x{i}
irb(main):013:1> value = %x['#{i} -version']
irb(main):014:1> val
irb(main):015:1>
Let me know
