The attached snapshot shows a slow class loading performed in AWT due to an extremely slow IO. Could be caused by ongoing Maven indexing?.

even the indexing thread seems to be hanging in low level io operations. Nothing really IO intensive seems to be happening in the indexing codebase (in the snapshot, there could be things happening before the snapshot was taken)
