Latest change made dur to https://issues.redhat.com/browse/WFCORE-5216 leads to an error for me on Solaris 10 SPARC:

/mbi/tools/jboss/23.x/bin/jboss-cli.sh: syntax error at line 84: `JBOSS_MODULEPATH=$' unexpected

Due to line 1 of the file /bin/sh is used for execution. 

Using either /bin/ksh or /bin/bash solves this issue for me.

Is the line 84 even needed ?

Lines 45 - 47: if JBOSS_MODULEPATH is not set, it's set to default value.

Line 66: in case of cygwin path is changed to window format

Line 84: set value to itself? 

From trace output (ksh -x):

++ eval echo '"/mbi/tools/jboss/23.x/modules"'
+++ echo /mbi/tools/jboss/23.x/modules
+ JBOSS_MODULEPATH=/mbi/tools/jboss/23.x/modules
