Fixing WKT process: parsing error and possible dead loop

[qifeng-bai]

This tool works with an area defined by 'current context', 'bounding box', etc, but It does not work with the area created by WKT

The task was created on Spatial-service, but stayed in the queue

Here is the WKT around Tas area:

POLYGON((
  143 -39,
  148 -39,
  148 -44,
  143 -44,
  143 -39
))

Issue 1:
SimpleRegion.parseSimpleRegion can parse properly:
POLYGON((143 -39,148 -39,148 -44,143 -44,143 -39))

but it cannot parse correctly:
POLYGON((\n 143 -39,\n 148 -39,\n 148 -44,\n 143 -44,\n 143 -39\n))

Temporary solution:

            //remove return/space that immediately occur after ','
            p = p.replaceAll('[\\n]+', '')
            //remove space that immediately occur after ','
            p = p.replaceAll(',[\\s]+', ',').trim()

We logged before and after

[Spatial-service] 2024-01-25 12:00:17.343  INFO au.org.ala.spatial.process.SlaveProcess [SlaveProcess.groovy:1117] : Parsing WKT

Issue 2:
However, if we are processing a complicated WKT, for example a WKT for Tasmania, there is a possibility that the process is in a dead loop in calculating grid cut:
