-------------------------------------
Summary: gemstone.gemfire.internal.cache.MinimumSystemRequirements
can't handle java version 1.7.0_101
Key: GEODE-1808
URL: https://issues.apache.org/jira/browse/GEODE-1808
Project: Geode
Issue Type: Bug
Components: general
Reporter: Sergio Valenti
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.
