[reginold]

I also met this problem,can you help me how to solve it please.

[rgtjf]

may be you should use the version 3.4.1 stanford-corenlp-full-2014-08-27.zip [http://nlp.stanford.edu/software/stanford-corenlp-full-2014-08-27.zip]

[treml05]

I use the version 3.4.1 stanford-corenlp-full-2014-08-27.zip
but got the same problem...

[Priya22]

I got the error with the latest release (3.6.0), but worked when I used 3.4.1 instead.

[aviatorBeijing]

Do these people even test their package before release to github?

[ioana-blue]

I had the same problem. Installing Oracle java 8 solved the problem for me.

[StatguyUser]

@ioana-blue i am using ubuntu and java 8, still i have the same error message. My java is

java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

[owiofwm2i]

same issue,anyone solve it?

[meggie-wong]

Same problem. I am using macos and java10. Could someone tell me how to solve it?

[JohnnyLim]

I found that the file default.properties wasn't in my project repo, and I added this file to the project. Then the problem was solved.

[kkac26]

Works with Oracle java 8 on Ubuntu 18.04:

openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-8u242-b08-0ubuntu3-18.04-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)

Doesn't work with Java 11!

[1033020837]

May it is the memory size too small...

[mohamc2022]

use openjdk version "1.8.0_92" worked for me.
