----------------------------------

> Key: GEODE-1808
> URL: https://issues.apache.org/jira/browse/GEODE-1808
> Project: Geode
> Issue Type: Bug
> Components: general
> Reporter: Sergio Valenti
> Fix For: 1.1.0
>
>
> We have recently updated out Java version to 1.7.0_101 on our server.
> However, after starting our java component which runs Gemfire version 8, we
> get the following log line:
> | FATAL | 20160821 18:05:30,626 | main |
> gemstone.gemfire.internal.cache.MinimumSystemRequirements | Java version
> older than 1.7.0_72.
> After looking at the source, it is apparent that the issue is in
> com.gemstone.gemfire.internal.lang.SystemUtils when dealing with java
> revisions which are 3 digits long
> public static boolean isJavaVersionAtLeast(String expectedVersion)
> {
> String actualVersionDigits =
> StringUtils.getDigitsOnly(System.getProperty("java.version"));
> String expectedVersionDigits =
> StringUtils.padEnding(StringUtils.getDigitsOnly(expectedVersion), '0',
> actualVersionDigits.length());
> try
> {
> return Long.parseLong(actualVersionDigits) >=
> Long.parseLong(expectedVersionDigits);
> }
> catch(NumberFormatException ignore)
> {
> return false;
> }
> }
> If you walk through this code with an expected version of java: 1.7.0_72 and
> an actual version of java: 1.7.0_101, it will create the following two long
> variables and compare them:
> actualVersionDigits "170101"
> expectedVersionDigits "170720"
> Which causes the comparison check to fail.
