maxHeapUsage value not read properly from config during EntryBuffers initialization

entryBuffers = new EntryBuffers(controller,
 this.conf.getInt("hbase.regionserver.hlog.splitlog.buffersize", 128 * 1024 * 1024),
 splitWriterCreationBounded);

In above case, EntryBuffers can't support maxHeapUsage in GB size.

The parameter type of the new EntryBuffers() is long, but the conf max value is INT.MAX. 

this is wrong？it should be getLong？
