Answer 1

You simply ran out of memory (128MB max):

128 Megabytes (MB)  =   134,217,728 Bytes (B)

If you have enough resources, I'd suggest to simply increase the JVM memory to e.g. 1GB max:

java -jar -Xms512M -Xmx1024M jaudiotagger-2.2.3.jar

This increases the Heap Size by passing JVM parameters -Xms (initial heap size) and -Xmx (max heap size)

This should do the job, but there's more parameters if you need to fine tune. See e.g.: Increase heap size in Java
