-------------------------------------
Summary: 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
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.
