exception while initializing IndexConfigWriter

[nischal reddy <ni...@gmail.com>]

Hi,

I am using lucene in my eclipse plugin, while initializing the
IndexConfigWriter i am getting an exception (see below). Interesting part
is when i am running a test.java class in the same plugin (with a main
method with call to the same method) everything is working fine.
But when i run the plugin as an eclipse application i am getting the below
exception.

i am using Lucene 4.4.

The Code where i am getting the error is:

IndexWriterConfig iwriter = new IndexWriterConfig(Version.LUCENE_44,
analyzer);

Exception trace:

!MESSAGE Unable to execute early startup code for an extension
