Another rJava library install error: rJava.rdb' is corrupt

I am having a time with java related packages this week. I finally got my RWeka working (see HERE), but now I'm having rJava issues.

The package seems to load up fine, but when I load the library I get the following:

Error in get(method, envir = home) : 
lazy-load database '/Library/Frameworks/R.framework/Versions/3.3/Resources/library/rJava/R/rJava.rdb' is corrupt
In addition: Warning messages:
1: In .registerS3method(fin[i, 1], fin[i, 2], fin[i, 3], fin[i, 4],  :
restarting interrupted promise evaluation
2: In get(method, envir = home) :
restarting interrupted promise evaluation
3: In get(method, envir = home) : internal error -3 in R_decompress1
Error: package or namespace load failed for ‘rJava’

Any ideas would be greatly appreciated!

If the package cannot be decompressed by R, then this error has occurred.

Suggestion#1:

  1. Try restarting R and running the app again.
  2. Sometimes for creation time of .rdb, may some issue occured.

Resource Link: Error in fetch(key) : lazy-load database

Suggestion#2: Quit and restart a clean R session from within R?

If you're in RStudio: command/ctrl + shift + F10

You can also use

.rs.restartR()

Suggestion#3:

Use a newer version of devtools, It may solve your issue sometimes.

Suggestion#4:

Check your JAVA_HOME is correctly set or not.

Use the followings one:

Sys.setenv(JAVA_HOME='...path to JRE...')

OR,

Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jdk1.7.0_51\\jre')

I did the following and it worked for me:

  1. Restart R session

.rs.restartR()

  1. Set JavaPath

Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jdk1.8.0_131\\jre')
