-----------------------+-------------------------
 I am upgrading xorg-libx11 with the +docs variant. The build fails on El
 Capitan but is OK on Big Sur.

 The build fails during the destroot phase where it is building the docs. I
 suspect it is a Java error like this one:

 {{{
 JVMJ9GC017E -Xmx too small, must be at least 1 Mbytes
 JVMJ9VM015W Initialization error for library j9gc29(2): Failed to
 initialize
 Error: Could not create the Java Virtual Machine.
 Error: A fatal exception has occurred. Program will exit.
 }}}

 There are errors like these below, but they also occur in the Big Sur
 build.

 {{{
 Error: unresolved olink: targetdoc/targetptr = 'icccm/Input_Focus'.
 Error: unresolved olink: targetdoc/targetptr = 'icccm/Input_Focus'.
 Error: unresolved olink: targetdoc/targetptr = 'icccm/icccm'.
 Error: unresolved olink: targetdoc/targetptr = 'icccm/icccm'.
 Error: unresolved olink: targetdoc/targetptr =
 'icccm/Changing_Window_State'.
 Error: unresolved olink: targetdoc/targetptr =
 'icccm/Changing_Window_State'.
 Error: unresolved olink: targetdoc/targetptr = 'xlfd/xlfd'.
 Error: unresolved olink: targetdoc/targetptr = 'xlfd/xlfd'.
 }}}

 I do not know how to increase the -Xmx value.
