tabulapdf extract_tables() error: java.lang.NoSuchMethodError

I've just installed tabulizer from github. I'm using MacOS Sierra. I also installed the legacy java from the link given on the install instructions: https://support.apple.com/kb/DL1572?locale=en_US.

When I use extract_tables(), I get the following error:

f <- system.file("examples", "data.pdf", package = "tabulizer")
extract_tables(f)

@jrcunning Thanks. Can you tell me what version of Java you installed? (The underlying java library - tabula - has some updates and it looks like they're causing Mac-specific issues.)

Facing the same issue. Would appreciate help.

Mar 30 '17 20:03 ahassanali

It seems the latest version of the tabula library is likely the issue. Consider re-installing an older version of tabulizerjars with, for example:

ghit::install_github("ropensci/[email protected]", verbose = TRUE)

Mar 31 '17 11:03 leeper

I installed tabulizerjarms v0.9.0 but still getting the same error:

Hey @leeper, tabula author here. Would love to help sorting this issue out, as the latest versions have significant perfomance and accuracy improvements.

Would it be possible to get a code snippet that reproduces the issue?

Thanks.

@leeper I'm quite sure that this only happens in Java 6.

Apr 11 '17 15:04 jazzido

Tabula-0.9.2.jar renders the same error as generated by tabulizer when Java 6 is the default JRE (see below). This is solved when switching to Java 8; unfortunately this does not make tabulizer work.

Apr 13 '17 15:04 jkeuskamp

@jkeuskamp Can you run java -version on a terminal? I'd like to confirm if that error occurs only with Java 6.

Apr 13 '17 15:04 jazzido

It is indeed Java 6: java version "1.6.0_65" Java(TM) SE Runtime Environment (build 1.6.0_65-b14-468-11M4833) Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-468, mixed mode)

Apr 13 '17 16:04 jkeuskamp

Thanks @jkeuskamp. Can't help you much about tabulizer, but tabula itself will work under a newer version of the Java virtual machine (7 or 8). Bear in mind that Java 6 has stopped receiving updates and support since 2013.

I'd recommend that you update your Java installation and try again.

Apr 13 '17 16:04 jazzido

@leeper @jzadra @jazzido
This solved the issue for me: I Installed JVM 8 and pointed RStudio to its installation as described here

to make tabulizer use JVM 8, edit the file ~/.profile and set the following env variables:

export JAVA_HOME=`/usr/libexec/java_home -v 1.8
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/server

then restart macOS or set the variables manually and restart RStudio.

Apr 14 '17 09:04 jkeuskamp

After trying the fix that solved things for jkeuskamp, I unfortunately still receive the "java.lang.NoSuchMethodError: java.lang.Integer.compare(II)I" error.

Apr 14 '17 22:04 supermdat

@supermdat could you confirm that java 8 is indeed called from R? You can check this by typing

library(rJava)
.jinit()
.jcall("java/lang/System", "S", "getProperty", "java.runtime.version")

this should return someting like

"1.8.0_121-b13"

The second number tells you whether java 6/7/8 is called.

Apr 15 '17 08:04 jkeuskamp

Thanks very much, @jkeuskamp . That is indeed the difference.

Running java -version from terminal gives:

java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

However, running this from within RStudio gives:

library(rJava)
.jinit()
.jcall("java/lang/System", "S", "getProperty", "java.runtime.version")
"1.6.0_65-b14-468-11M4833"

I've done some searching but don't understand well how to have R call Java 8. I'll continue researching, but would appreciate any tips.

Apr 15 '17 15:04 supermdat

@leeper Just noticed that the README.Rmd mentions:

On Mac OS, you may need to install a particular version of Java prior to attempting to install tabulizer.

You probably want to remove this line, as tabulizer now requires Java 7/8

Apr 16 '17 14:04 jkeuskamp

@supermdat

Found similar issue on rJava GitHub

Managed to force rJava to use 1.8 by running R CMD javareconf JAVA_CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers then reinstalling rJava from source with install.packages("rJava", "http://rforge.net/", type="source")

If you run into issues then loading rJava with something similar to error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rJava/libs/rJava.so':

you then need to link the files together using: source sudo ln -f -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

And finally, it should load and show 1.8, which on my system meant I could run tabulizer successfully(!),

Apr 20 '17 09:04 lissahyacinth

Hi all,

Would there be any way at all of getting tabulizer to work with Java 6? I'm having the above NoSuchMethodError issue but on Windows with Java 6 installed (unfortunately can't update Java very easily as it's a work computer without admin rights) Perhaps an older version of tabulizer and/or tabulizerjars?

Thanks for any help anyone can offer!

Apr 20 '17 16:04 peterblair

@peterblair You can definitely try pulling an older version of tabulizerjars; the versions are all available as releases on GitHub and they are numbered to align with tabula-java release numbers, e.g.: ghit::install_github("ropensci/[email protected]")

Apr 20 '17 20:04 leeper

Just for info, installing tabulizerjars v0.8.0 works with Java 6 on Windows. Thanks very much!
