Solution:
<lang groovy>def rawTrace = { Thread.currentThread().stackTrace }</lang>
Test: (demonstrates, among other things, continued execution after generating stack trace)
<lang groovy>def trace = rawTrace().collect {
def props = it.properties
def keys = (it.properties.keySet() - (new Object().properties.keySet()))
props.findAll{ k, v -> k in keys }
}
def propNames = trace[0].keySet().sort()
def propWidths = propNames.collect { name -> [name, trace.collect{ it[name].toString() }].flatten()*.size().max() }
propNames.eachWithIndex{ name, i -> printf("%-${propWidths[i]}s ", name) }; println ''
propWidths.each{ width -> print('-' * width + ' ') }; println ''
trace.each {
propNames.eachWithIndex{ name, i -> printf("%-${propWidths[i]}s ", it[name].toString()) }; println ''
}</lang>
Output:
