----------------------------------
Fix Version/s: 1.12.0
Resolution: Duplicate
> method to determine major java version causes bootstrap failure
> ---------------------------------------------------------------
>
> Key: NIFI-7727
> URL: https://issues.apache.org/jira/browse/NIFI-7727
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.11.4
> Environment: windows, java 11
> Reporter: Evert Bevernage
> Priority: Minor
> Fix For: 1.12.0
>
>
> Using java 11 (openjdk 11 + 28) run-nifi.bat fails with the following message:
> {code:java}
> C:\Programs\nifi-1.11.4\bin>run-nifi.bat
> Exception in thread "main" java.lang.StringIndexOutOfBoundsException:
> nd -1, length 2
> at java.base/java.lang.String.checkBoundsBeginEnd(String.java
> at java.base/java.lang.String.substring(String.java:1874)
> at org.apache.nifi.bootstrap.RunNiFi.start(RunNiFi.java:1040)
> at org.apache.nifi.bootstrap.RunNiFi.main(RunNiFi.java:240)
> {code}
>
>
> I believe the issue is caused as follows: nifi bootstrap tries to identify
> the major java version using a substring statement:
>
> {code:java}
> if (Integer.parseInt(runtimeJavaVersion.substring(0,
> runtimeJavaVersion.indexOf('.'))) >= 11) ...
> {code}

> However the version reported by openjdk 11+28 is “11”, this string doesn’t
> contain a period. Causing the failure. Using openjdk 11.0.2 resolves the
> issue.
