Dear,

I tried to index a springboot project, all the jars is around 100MB,

The follow exception was thrown by lucene and meghanada-server,

I have tried to delete all the index and caches and start from scratch, but still get this error.

Here is my settings in Emacs:

(require 'meghanada)
(add-hook 'java-mode-hook
          (lambda ()
            (meghanada-mode t)
            (gradle-mode t)
            (add-hook 'before-save-hook 'delete-trailing-whitespace)))
(add-hook 'groovy-mode-hook
          (lambda ()
            (gradle-mode t)))

(global-set-key (kbd "H-r") 'meghanada-reference)
(setq company-meghanada-auto-import t)
(setq company-meghanada-show-annotation t)
(setq meghanada-full-text-search-enable t)
(setq meghanada-server-remote-debug t)

(setq meghanada-skip-build-subprojects nil)
(setq meghanada-cache-in-project nil)
(setq meghanada-server-jvm-option
      "-Xms512m -Xmx1024m -XX:ReservedCodeCacheSize=480m -XX:+UseConcMarkSweepGC -XX:SoftRefLRUPolicyMSPerMB=50 -ea -Dsun.io.useCanonCaches=false")

Is there any possible causing and resolving to this issue?

Thanks.

I think it is a problem of lucene...
Could you please tell me which repository can reproduce the problem?
