Description

Using java 11 (openjdk 11 + 28) run-nifi.bat fails with the following message:

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)

 

 

I believe the issue is caused as follows: nifi bootstrap tries to identify the major java version using a substring statement:

 

if (Integer.parseInt(runtimeJavaVersion.substring(0, runtimeJavaVersion.indexOf('.'))) >= 11) ...

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.
